That is the size of the reused\nreply buffer, not the number of bytes actually received.\n\nA truncated reply can therefore pass ceph_decode_need() and decode the\nsecond u64 from stale tail bytes

resolved:\n\nopenrisc: signal: do not restore privileged SR bits on sigreturn\n\nrestore_sigcontext() copies the whole supervision register (SR) from the\nsignal frame and only clears SPR_SR_SM before the value is reloaded into\nthe hardware SR (through ESR and l.rfe) on the return to user space. All\nother SR bits are left under user control.\n\nAn unprivileged task can thus return from a signal handler through a\ncrafted sigframe that clears SPR_SR_DME. With the data MMU disabled the\nCPU performs no translation or protection on data accesses, so the task\ngains read and write access to arbitrary physical memory, a local\nprivilege escalation. SPR_SR_IME, SPR_SR_SUMRA, SPR_SR_LEE, SPR_SR_EPH\nand the cache-enable bits are exposed the same way. The ptrace GPR regset\nalready refuses any change to SR for exactly this reason.\n\nRestore only the arithmetic flag bits (F, CY, OV) from the signal frame\nand take every privileged control bit from the SR the kernel saved on\nsignal entry.\n\nVerified with qemu-system-or1k -M or1k-sim: before this change an\nunprivileged PoC clears SPR_SR_DME in rt_sigreturn and writes a marker to\nphysical address 0x03000000 (beyond the kernel's mem=32M); afterwards the\nsame PoC receives SIGSEGV and physical memory is unchanged.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

This causes a division by\nzero when calculating num_dpb_buffer in H264 and H264 Perf decode\npaths.\n\nAdd validation to reject frames with width < 16 or height < 16\nbefore performing any

resolved:\n\nbtrfs: reject free space cache with more entries than pages\n\nWhen loading a v1 free space cache, __load_free_space_cache() takes\nnum_entries and num_bitmaps straight from the on-disk\nbtrfs_free_space_header. That header is stored in the tree_root under a key\nwith type 0, which the tree-checker has no case for, so neither count is\nvalidated before the load trusts it.\n\nThe load loops num_entries times and maps the next page whenever the current\none runs out, going through io_ctl_check_crc() -> io_ctl_map_page(), which\ndoes io_ctl->pages[io_ctl->index++]. But pages[] is allocated in\nio_ctl_init() from the cache inode's i_size, not from num_entries:\n\n\tnum_pages = DIV_ROUND_UP(i_size_read(inode), PAGE_SIZE);\n\tio_ctl->pages = kcalloc(num_pages, sizeof(struct page *), GFP_NOFS);\n\nSo if num_entries claims more records than the pages can hold, io_ctl->index\nruns off the end of pages[]. The write side never hits this because\nio_ctl_add_entry() and io_ctl_add_bitmap() both stop once\nio_ctl->index >= io_ctl->num_pages; the read side just never had the same\ncheck.\n\nTo trigger it, take a clean cache (num_entries = here), set num_entries\nin the header to 0x10000, and fix up the leaf checksum so it still passes\nthe tree-checker. The cache inode has i_size = 65536, so num_pages is 16 and\npages[] is a 16-pointer (kmalloc-128) array. The load now tries to read\n65536 entries, io_ctl->index walks up to 16, and pages[16] is read past the\narray:\n\n BUG: KASAN: slab-out-of-bounds in io_ctl_check_crc (fs/btrfs/free-space-cache.c:420 fs/btrfs/free-space-cache.c:565)\n Read of size 8 at addr ffff88800c833a80 by task kworker/u8:3/58\n io_ctl_check_crc (fs/btrfs/free-space-cache.c:420 fs/btrfs/free-space-cache.c:565)\n __load_free_space_cache (fs/btrfs/free-space-cache.c:655 fs/btrfs/free-space-cache.c:820)\n load_free_space_cache (fs/btrfs/free-space-cache.c:1017)\n caching_thread (fs/btrfs/block-group.c:880)\n btrfs_work_helper (fs/btrfs/async-thread.c:312)\n process_one_work\n worker_thread\n kthread\n ret_from_fork\n\nfree-space-cache.c:420 is io_ctl_map_page(), inlined into io_ctl_check_crc()\nat line 565, which is why that is the frame KASAN names. The out-of-bounds\nslot is then treated as a struct page and handed to crc32c(), so the bad\nread turns into a GP fault.\n\nAdd the missing check to io_ctl_check_crc(), which is where both the entry\nloop and the bitmap loop end up. When num_entries is too large the load now\nfails like any corrupt cache: __load_free_space_cache() drops it and rebuilds\nthe free space from the extent tree, so a valid cache is never rejected.",

"text": "In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: reject negative CO-RE accessor indices in bpf_core_parse_spec()\n\nCO-RE accessor strings are colon-separated indices that describe a path\nfrom a root BTF type to a target field, e.g. \"0:1:2\" walks through\nnested struct members. bpf_core_parse_spec() parses each component with\nsscanf(\"%d\"), so negative values like -1 are silently accepted. The\nsubsequent bounds checks (access_idx >= btf_vlen(t)) only guard the\nupper bound and always pass for negative values because C integer\npromotion converts the __u16 btf_vlen result to int, making the\ncomparison (int)(-1) >= (int)(N) false for any positive N.\n\nWhen -1 reaches btf_member_bit_offset() it gets cast to u32 0xffffffff,\nproducing an out-of-bounds read far past the members array. A crafted\nBPF program with a negative CO-RE accessor on any struct that exists in\nvmlinux BTF (e.g. task_struct) crashes the kernel deterministically\nduring BPF_PROG_LOAD on any system with CONFIG_DEBUG_INFO_BTF=y\n(default on major distributions).

resolved:\n\nInput: synaptics-rmi4 - zero report size on F54 work error\n\nIn rmi_f54_work(), if an error occurs during report request or command\nverification, the code jumped directly to the 'error' label, bypassing\nthe 'abort' label where f54->report_size was normally zeroed out.\n\nThis left f54->report_size containing its previous successful payload\nsize. If a user then altered the V4L2 format to a smaller size, and a\nsubsequent run failed, rmi_f54_buffer_queue() would copy the stale,\nlarger payload size into the shrunken V4L2 buffer, causing a heap\nbuffer overflow.\n\nFix this by merging the 'abort' and 'error' labels into a single 'out'\nexit path, and ensuring that f54->report_size is always set to 0 on\nfailure by checking for error and zeroing the local report_size first.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\nbinfmt_elf_fdpic: only honour the first PT_INTERP\n\nThe program header scan handles PT_INTERP from a switch nested in the\nscan loop, so its break leaves the switch and not the loop. A binary\ncarrying more than one PT_INTERP runs the case again and overwrites both\ninterpreter_name and interpreter. The previous name allocation leaks and\nso does the previous interpreter reference, along with the write denial\nopen_exec() took on it. The denial is never released, so the file stays\nunwritable for as long as the system runs.\n\nAn unprivileged caller reaches this with a crafted binary and repeats it\nat will. binfmt_elf stops at the first PT_INTERP. Do the same here.\n\nThe flaw dates back to the driver's introduction in the pre-git history\ntree introduced in v2.6.11 by 91808d6ebe39 (\"[PATCH] FRV: Add FDPIC ELF\nbinary format driver\").",

memcpy(bytes, &raw->msg[idx], num_bytes);\n\nwithout checking that idx + num_bytes <= raw->curlen. raw->msg[] is\n256 bytes; if a malicious or misbehaving MST hub sets num_bytes larger\nthan the remaining payload, the memcpy reads past the received data\ninto whatever follows in raw->msg[].\n\ndrm_dp_sideband_parse_remote_i2c_read_ack() has the same flaw (noted\nwith a /* TODO check */ comment since the code was introduced).\n\nFix both functions by using a single combined check\n(idx + num_bytes > curlen) before each memcpy. Since num_bytes is u8,\nit is always >= 0, so this strictly subsumes the simpler idx > curlen\nform and no separate step is needed.\n\n[added missing fixes tag]", "title": "Vulnerability description"

resolved:\n\nwifi: mwifiex: bound uAP association event IEs to the event buffer\n\nmwifiex_process_uap_event() handles EVENT_UAP_STA_ASSOC by exposing the\n(re)association request IEs that the firmware copies into the event:\n\n\tsinfo->assoc_req_ies = &event->data[len];\n\tlen = (u8 *)sinfo->assoc_req_ies - (u8 *)&event->frame_control;\n\tsinfo->assoc_req_ies_len = le16_to_cpu(event->len) - (u16)len;\n\nevent->len is supplied by the device firmware and is never validated,\nand the subtraction is unchecked. assoc_req_ies points into\nadapter->event_body[MAX_EVENT_SIZE], a fixed-size array embedded in the\nkmalloc()'d struct mwifiex_adapter.\n\nOn the ap_11n_enabled path mwifiex_set_sta_ht_cap() walks these IEs with\ncfg80211_find_ie(), whose for_each_element() loop dereferences each\nelement header. A firmware-reported event->len larger than the bytes\nactually received makes assoc_req_ies_len describe IEs that extend past\nevent_body, so the walk reads out of the adapter slab object, a\nslab-out-of-bounds read (KASAN: slab-out-of-bounds in cfg80211_find_ie).\nAn event->len smaller than the header instead makes the int subtraction\nnegative, which wraps to a huge size_t when stored in assoc_req_ies_len.\nThe same length is handed to cfg80211_new_sta(), so a more modest\nover-claim can also copy stale event_body bytes into the\nNL80211_CMD_NEW_STATION notification.\n\nA malicious or malfunctioning mwifiex device (USB/SDIO/PCIe) can deliver\nsuch an event while the interface is in AP/uAP mode.\n\nValidate event->len before use: reject a length that underflows the\nheader or that would place the IEs outside the event_body[] buffer the\nevent was copied into. event->len here is struct mwifiex_assoc_event.len,\na payload field internal to this event, not the transport frame length,\nso it is validated in this handler rather than at the generic\nMWIFIEX_TYPE_EVENT receive path, which only sees the event cause and the\ntransport frame length. The bound is against event_body[MAX_EVENT_SIZE]\nrather than the actually-received length because the transports store the\nevent differently (USB and SDIO leave the 4-byte event header in\nevent_skb, PCIe strips it via skb_pull), whereas event_body is the single\nfixed buffer all of them copy the event into. This is the event-path\nanalogue of the receive-path bounds checks added in commit 119585281617\n(\"wifi: mwifiex: Fix OOB and integer underflow when rx packets\").", "title": "Vulnerability

resolved:\n\nnet/sched: cls_route: fix fastmap use-after-free on filter\n\nThe route4 classifier maintains a 16-slot fastmap cache that stores raw\nstruct route4_filter pointers indexed by (id, iif). The reader\n(route4_classify) populates this cache via route4_set_fastmap() for every\nclassified packet that hits a filter. The writer (route4_delete,\nroute4_change) clears the cache via route4_reset_fastmap() before\nRCU-deferred kfree of the filter.\n\nThis creates a UAF race:\n 1. Reader walks the RCU-protected bucket chain, finds filter f\n 2. Writer unlinks f, calls route4_reset_fastmap(), then tcf_queue_work()\n 3. Reader calls route4_set_fastmap() and writes f into the cache\n *after* the writer's reset, caching a pointer about to be freed\n 4. After the RCU grace period, kfree(f) executes\n 5. Next classified packet on the same (id, iif) tuple hits the stale\n fastmap entry and reads f->res from freed memory\n\nReproduced with an mdelay(100) accelerator in route4_set_fastmap() and a\nconcurrent add/delete stress test (provided by both zdi and Santosh).\nBoth triggered KASAN slab-use-after-free reports in the route4 fastmap\npaths.\n\nFix:\nIntroduce a per-filter boolean dying flag to suppress stale fastmap\nrepublishing by in-flight readers.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\nusb: gadget: dummy_hcd: prevent fifo_req reuse during giveback\n\ndummy_hcd embeds a single shared usb_request (dum->fifo_req) that the\n\"emulated single-request FIFO\" fast-path in dummy_queue() reuses for\nsmall IN transfers: it copies the caller's request into it\n(req->req = *_req) and queues it, treating list_empty(&fifo_req.queue)\nas \"the slot is free\".\n\nThe completion side (dummy_timer/transfer/nuke/dummy_dequeue) follows\nthe standard pattern: list_del_init(&req->queue) unlinks the request,\nthen the lock is dropped and usb_gadget_giveback_request() invokes\nreq->complete(). But list_del_init() makes fifo_req.queue look empty\n*before* the completion callback returns, so a concurrent dummy_queue()\non another CPU sees the slot as free, reuses fifo_req and runs\nreq->req = *_req -- overwriting req->complete while dummy_timer is\nmid-calling it. The indirect call then jumps to a clobbered pointer,\ncausing a general protection fault / page fault in dummy_timer\n(syzkaller extid faf3a6cf579fc65591ca). The clobbering write is an\nin-bounds memcpy on a live shared object, so KASAN cannot flag it.\n\nAdd a fifo_req_busy bit covering the shared request's whole lifetime:\nset it in dummy_queue() when the FIFO fast-path takes fifo_req (making\nit the fast-path guard, replacing the list_empty(&fifo_req.queue)\ntest), and clear it after the completion callback has returned, via a\ndummy_giveback() helper used at all four gadget-request giveback\nsites. The shared slot can no longer be reused until its completion\ncallback has finished.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

mapping.\nInstalling a replacement buffer then overwrites the slot references and\nleaks both resources.\n\nKeep the current slot intact and return budget so NAPI retries the same\nbuffer.

immediately\nreleases the lock without holding a reference to the socket. A concurrent\nclose() can free the socket between the lock release and the subsequent\nsk->sk_state access, resulting in a use-after-free.\n\nOther functions in the same file (sco_sock_timeout(), sco_conn_del())\ncorrectly use sco_sock_hold() to safely hold a reference under the lock.\n\nFix by using sco_sock_hold() to take a reference before releasing the\nlock, and adding sock_put() on all

>=\n\t\t\tiint->ima_hash->length)\n\nsizeof() yields size_t, so the usual arithmetic conversions promote\nthe whole left-hand side to unsigned 64-bit before the subtraction\nruns. For a truncated xattr this underflows instead of going negative:\na 1-byte IMA_XATTR_DIGEST_NG xattr (xattr_len == 1, hash_start == 1)\nturns \"1 - 1 - 1\" into SIZE_MAX, which is trivially >= ima_hash->length.\nThe check then passes and the following memcmp() reads\niint->ima_hash->length bytes starting past the end of the buffer\nvfs_getxattr_alloc() allocated for it.\n\nNothing upstream clamps xattr_len back into a safe range first:\nima_get_hash_algo() only special-cases xattr_len < 2 to pick a default\nalgorithm, and evm_verifyxattr() returns INTEGRITY_UNKNOWN rather than\nfailing when no HMAC key is loaded, so a truncated security.ima value\nreaches the length check as-is.\n\nRewrite the comparison so every operand stays a signed int and no\nimplicit conversion to size_t can

but pcpu_chunk_populated()\nuses it to set chunk->populated, whose size is pcpu_unit_pages, bitmap. \nSince bit N in chunk->populated means page offset N inside every unit is\nbacked. When nr_units > 1, the function writes beyond chunk->populated. \nFix it by using chunk->nr_pages.\n\nIt also fixes the global pcpu_nr_empty_pop_pages accounting, since\npcpu_balance_free() only iterates up to chunk->nr_pages.\n\nCommit a63d4ac4ab609 (\"percpu: make percpu-km set chunk->populated bitmap\nproperly\") introduced the bitmap overflow issue. Later, commit\nb539b87fed37f (\"percpu: implmeent pcpu_nr_empty_pop_pages and\nchunk->nr_populated\") added pcpu_nr_empty_pop_pages and caused the\naccounting issue.", "title": "Vulnerability

for a\npost-firmware one.\n\nuea_disconnect() instead tells the two apart by the number of interfaces\nof the active configuration (a pre-firmware device exposes a single\ninterface, ADI930 has 2 and eagle has 3), and casts the interface data\naccordingly.\n\nBecause the two handlers use different criteria, a crafted device that\nadvertises a pre-firmware id together with a multi-interface descriptor\n(or a post-firmware id with a single interface) makes them disagree: the\nsmall 'struct completion' stored by uea_probe() is then passed to\nusbatm_usb_disconnect(), which casts it to

The buffer is\ngetting removed from the list after it is unmapped from DSP. This can\ncreate potential race conditions if multiple threads invoke unmap\nconcurrently, where one thread may remove the entry from the list while\nanother thread's unmap operation is still ongoing.\n\nFix this by removing the buffer entry from the list before calling the\nunmap operation. If the unmap fails, the entry is re-added to the list\nso that userspace can retry the unmap, or alternatively, the buffer\nwill be cleaned up during device release when the DSP process is torn\ndown

But for the controls that select\nthe CROP/COMPOSE/SCALE capability that is not checked.\n\nOnly when streaming starts will they be set to 'grabbed' and it is\nimpossible to change the control, but between REQBUFS and STREAMON you\nare still allowed to set these controls. Since vivid_update_format_cap/out\nwill change the format, this can cause unexpected results.\n\nBesides adding these checks, also add a WARN_ON in\nvivid_update_format_cap/out() if the queue is busy.\n\nI'm 90% certain that this is the cause of this syzbot bug:\n\nhttps://syzkaller.appspot.com/bug?extid=dac8f5eaa46837e97b89\n\nBut since we never have reproducers, it is hard to be certain.

If that allocation fails, the function\njumps to fail and calls brcmf_sdio_remove().\n\nbrcmf_sdio_remove() unconditionally cancels bus->datawork. Initialize the\nwork item before the first failure path that can reach brcmf_sdio_remove(),\nso the cleanup path always observes a valid work object.\n\nThis issue was found by our static analysis tool and then confirmed by\nmanual review of the probe error path and the remove-time work drain. The\nproblem pattern is an early setup failure that reaches a cleanup helper\nwhich cancels an embedded work item before its initializer has run.\n\nA QEMU PoC forced alloc_ordered_workqueue() to fail at the same point in\nbrcmf_sdio_probe(), before INIT_WORK(&bus->datawork) is reached.

resolved:\n\nlibceph: Avoid using invalid osd indices from primary_temp\n\nA corrupted osdmap received from a Ceph monitor or OSD may contain osd\nindices in its pg_temp, primary_temp, pg_upmap, and pg_upmap_items parts\nthat don't exist, i.e., that are greater than max_osd or smaller than\nCEPH_HOMELESS_OSD (-1). These indices are used to create the up and\nacting set in ceph_pg_to_up_acting_osds(), called from calc_target().\nWhile most of these osd indices are checked, the one from primary_temp\nis not. Subsequently, this may lead to calc_target() returning this\n(potentially invalid) index as target osd for a (linger) request.\nBecause the osd_state, osd_weight, and osd_addr arrays only contain\nmax_osd entries (with indices 0 to max_osd -1), this leads to\nout-of-bounds accesses when trying to read values from these arrays.\n\nThis patch fixes the issue by adding a check to get_temp_osds(), so that\nonly valid osd indices from primary_temp are used, and it falls back to\nusing the primary from pg_temp or the up set if it is invalid.\n\n[ idryomov: changelog ]", "title":

being written to\nbefore performing the swap. However, there exists a race window where\nthis check can be bypassed:\n\n ring_buffer_lock_reserve\n cpu_buffer = buffer->buffers[cpu]; // cpu_buffer_a\n rb_reserve_next_event\n rb_start_commit // inc committing\n if (unlikely(READ_ONCE(cpu_buffer->buffer) != buffer)) {...}\n __rb_reserve_next\n rb_move_tail\n rb_end_commit(cpu_buffer); // dec committing => 0\n /* interrupt hits here, successfully swaps! */\n local_inc(&cpu_buffer->committing);\n\n ring_buffer_unlock_commit\n cpu_buffer = buffer->buffers[cpu]; // cpu_buffer_b\n rb_commit\n rb_end_commit\n RB_WARN_ON(cpu_buffer, !local_read(&cpu_buffer->committing))\n // triggers warning\n\nThe committing counter can temporarily drop to 0 during a single write\noperation (within rb_move_tail), creating a window where swap can\nsucceed even though the write is still in progress. This leads to\ninconsistent buffer state and triggers the RB_WARN_ON in rb_commit().\n\nReplace the committing counter check with current_context checks, which\nare set at the entry of

They differ once the device is\ncreated in or moved to a netns other than the one the request runs in.\nThe rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev),\nso a caller privileged

geneve_quiesce()/geneve_unquiesce() pair\nreopen the underlay sockets in that netns (geneve_sock_add() uses\ngeneve->net), so the same reasoning as the tunnel changelink series\napplies here.\n\nGate

Several early probe failures then unwind\nthrough wanxl_pci_remove_one(), including failure to allocate the coherent\nstatus area or to restore the DMA mask.\n\nwanxl_pci_remove_one() unconditionally calls wanxl_reset(), and\nwanxl_reset() dereferences card->plx. On those early failures card->plx\nis still NULL, so the error path can dereference a NULL MMIO pointer.\n\nOnly issue the hardware reset once the BAR mapping exists. The remaining\ncleanup in wanxl_pci_remove_one() already checks whether later resources\nwere allocated.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.",

resolved:\n\nnet/x25: fix use-after-free of the socket by its timers\n\nThe x25 timers are armed with mod_timer() and cancelled with\ntimer_delete(), so a pending timer holds no reference on the socket and a\ncancel does not wait for a callback already running on another CPU.\n\nx25_heartbeat_expiry() also rearms unconditionally, so it can reinstall\nsk->sk_timer after __x25_destroy_socket() has passed its cancel point.\nThe following __sock_put() frees the socket while the timer is still\nqueued, and the next expiry uses freed memory. KASAN reports a\nslab-use-after-free on the kmalloc-2k object freed by close().\n\ntimer_delete_sync() cannot be used here: x25_heartbeat_expiry() and\nx25_timer_expiry() both reach the cancels from inside the timer they\nwould wait on, through __x25_destroy_socket() and x25_disconnect().\n\nArm the timers with sk_reset_timer() and cancel them with sk_stop_timer()\nso that an armed timer owns a reference, and release it in both expiry\nhandlers. Rearm the heartbeat only while sk_hashed(sk) is still true,\nsince __x25_destroy_socket() unlinks the socket before dropping it. Arm\nthe deferred destroy timer the same way and drop its reference in\nx25_destroy_timer().\n\nReproduced on net with KASAN, with the heartbeat period shortened so the\nwindow recurs. With this patch the reproducer no longer triggers a\nreport and /proc/net/x25 drains.\n\nDiscovered by XBOW, triaged by Baul Lee ", "title": "Vulnerability description" } ], "product_status": {

resolved:\n\nwifi: ath9k: hif_usb: don't dereference hif_dev after re-arming firmware request\n\nath9k_hif_request_firmware() re-arms an asynchronous firmware load via\nrequest_firmware_nowait(), passing hif_dev as the completion context, and\nthen still dereferences hif_dev:\n\n\tdev_info(&hif_dev->udev->dev, \"ath9k_htc: Firmware %s requested\\n\",\n\t\t hif_dev->fw_name);\n\nThe re-armed callback ath9k_hif_usb_firmware_cb() runs on the \"events\"\nworkqueue and, when the firmware is missing, walks the retry chain into\nath9k_hif_usb_firmware_fail() -> complete_all(&hif_dev->fw_done). That\nreleases the wait_for_completion(&hif_dev->fw_done) in a concurrent\nath9k_hif_usb_disconnect(), which then kfree()s hif_dev. The trailing\ndev_info() in the frame that re-armed the request can therefore read freed\nmemory (hif_dev->udev, the first field of struct hif_device_usb):\n\n BUG: KASAN: slab-use-after-free in ath9k_hif_request_firmware\n Read of size 8 ... by task kworker/...\n ath9k_hif_request_firmware\n ath9k_hif_usb_firmware_cb drivers/net/wireless/ath/ath9k/hif_usb.c:1247\n request_firmware_work_func\n Allocated by ...:\n ath9k_hif_usb_probe drivers/net/wireless/ath/ath9k/hif_usb.c\n Freed by ...:\n ath9k_hif_usb_disconnect -> kfree drivers/net/wireless/ath/ath9k/hif_usb.c\n\nThe fw_done barrier only makes disconnect wait for the firmware chain to\n*terminate*; it does not protect the outer ath9k_hif_request_firmware()\nframe that re-armed the request and keeps touching hif_dev afterwards.\n\nDrop the post-request dev_info(): it is the only use of hif_dev after the\nasync request is armed, and it is purely informational (the dev_err() on the\nfailure path runs only when request_firmware_nowait() did not arm a callback,\nso hif_dev is still alive there).\n\nThis was first reported by syzbot as a single, non-reproduced crash that was\nlater auto-obsoleted, and was independently rediscovered by the reFuzz fuzzer,\nwhich produced a C reproducer (USB-gadget connect/disconnect of an ath9k_htc\ndevice whose firmware download fails).

A malfunctioning, malicious or counterfeit controller\n(or an attacker tampering with the I2C bus) can report a packet_size of\nup to 255, so __mms114_read_reg() writes up to 175 bytes past the end

If that happens\nfor a matching table entry, the resource lookup still returns success and\nthe following trylock dereferences a NULL mutex pointer while opening the\nresource.\n\nnfp_resource_acquire() already treats failure to allocate the table mutex\nas -ENOMEM.

to build a fake\nend pointer (snaptrace + snaptrace_len) that is later handed to\nceph_update_snap_trace() in the CEPH_CAP_OP_IMPORT case:\n\n snaptrace = h + 1;\n snaptrace_len = le32_to_cpu(h->snap_trace_len);\n p = snaptrace + snaptrace_len;\n ...\n case CEPH_CAP_OP_IMPORT:\n if (snaptrace_len) {\n ...\n if (ceph_update_snap_trace(mdsc, snaptrace,\n snaptrace + snaptrace_len,\n false, &realm)) { ... }\n\nceph_update_snap_trace() then decodes a struct ceph_mds_snap_realm\nfrom snaptrace using ceph_decode_need(&p, e, sizeof(*ri), bad)\nwith the attacker-supplied fake end e == snaptrace + snaptrace_len.\nWith snaptrace_len == 0xFFFFFFFF the bound check is trivially\nsatisfied, ri = p reads sizeof(struct ceph_mds_snap_realm) past\nthe legitimate msg->front buffer, and ri->num_snaps /\nri->num_prior_parent_snaps then drive further out-of-bounds\nreads of the encoded snap arrays.\n\nThe eleven msg_version >= 2 .. msg_version >= 12 decoder blocks\nabove the op switch each catch this OOB through their\nceph_decode_*_safe() / ceph_decode_need() helpers, but they sit\nbehind a hdr.version-gated if, so a malicious or compromised\nMDS that sets msg->hdr.version = 1 reaches the IMPORT path with\nno version-gated decoder having validated snap_trace_len. The\nshape has been present since ceph_handle_caps() was introduced.\n\nValidate snap_trace_len against the message front buffer before\nconsuming it, using the canonical ceph_decode_need() / ceph_has_room()\nhelper. The helper bounds the length with subtraction (n <= end - p,\nguarded by end >= p) rather than pointer addition, so it is wrap-safe\nfor the attacker-controlled u32 length on 32-bit builds where\np + snap_trace_len could overflow the address space. This matches the\nrest of the ceph decode path (e.g. the pool_ns_len check a few lines\nbelow), and the existing goto bad cleanup already covers this exit\npath.", "title": "Vulnerability description"

resolved:\n\nhwmon: (nct6775-core) Prevent access to unsupported weight registers\n\nSashiko reports:\n\nDuring initialization of the nct6116 chip, the driver sets data->pwm_num\nto 5. However, it assigns several NCT6106 register arrays (such as\nNCT6106_REG_WEIGHT_DUTY_STEP, NCT6106_REG_WEIGHT_TEMP_SEL, and\nNCT6106_REG_WEIGHT_TEMP_*) to data->REG_PWM and data->REG_WEIGHT_TEMP.\nThese arrays only contain 3 elements.\n\nIn nct6775_update_pwm(), the driver iterates up to data->pwm_num. If\ndata->has_pwm has bits 3 or 4 set (which is structurally possible for\nnct6116), the loop attempts to read elements at index 3 and 4 from these\n3-element arrays. This results in a global out-of-bounds read, which can\nbe caught by KASAN.\n\nFurthermore, the driver uses these garbage out-of-bounds values as\nhardware register addresses for subsequent read and write operations. This\nleads to invalid hardware register access, potentially causing hardware\nmisconfiguration or system crashes.\n\nThe underlying problem is that the chip does support up to five fan\ncontrol channels, but only the first three support weight control.\nFix the problem by extending the affected weight register arrays with\nzeroed fields. The driver uses zeroed register addresses to determine\nif a register is supported or not, and skips accesses for unsupported\nregisters.", "title": "Vulnerability description" } ], "product_status":

resolved:\n\nnet: openvswitch: reallocate update replies for mismatched IDs\n\novs_flow_cmd_new() preallocates the optional reply skb before it takes\novs_mutex and before it knows which existing flow will be updated.\n\nThat is normally fine because the skb is sized from the request flow\nidentifier. That identifier also becomes the inserted flow's identifier.\nFor updates, however, a request with a UFID may miss the UFID lookup and\nthen fall back to the flow key lookup. That lookup can legitimately find\nan existing key-identified flow. UFIDs are optional and the flow key is\nthe primary identifier.\n\nFor echoed replies, ovs_flow_cmd_fill_info() writes the matched flow's\nidentifier, not the request identifier used for the preallocation. A short\nrequest UFID can therefore leave too little room for the key identifier.\nThe fill can then fail with -EMSGSIZE and hit the BUG_ON(error < 0) in the\nupdate path.\n\nOnce the update target has been resolved, reallocate the reply skb if the\nmatched flow needs a larger reply than the request identifier allowed. Do\nthis before replacing the actions so the request can still fail cleanly if\nthe rare extra allocation fails.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

filter content\nwhile bcm_rx_handler(), bcm_rx_timeout_handler() or bcm_rx_thr_handler()\nrun concurrently on incoming CAN traffic.\n\nProtect the timer (ival1/ival2/kt_ival1/kt_ival2/kt_lastmsg) and filter\n(nframes/flags/frames/last_frames) updates in bcm_rx_setup() with a new\nper-op bcm_rx_update_lock, taken with the matching scope in the RX\nhandlers. memcpy_from_msg() is staged into a temporary buffer before the\nlock is taken, since it can sleep and must not run under a spinlock.\n\nhrtimer_cancel() is always called without bcm_rx_update_lock held, since\nbcm_rx_timeout_handler()/bcm_rx_thr_handler() take the same lock and a\nrunning callback would otherwise deadlock against the canceller.\n\nAlso close a related race: bcm_rx_setup() cleared the RTR flag in the\nstored reply frame's can_id as a separate, unprotected step after the\nframe content was already installed, so a concurrent bcm_rx_handler()\ncould transmit a stale reply with CAN_RTR_FLAG still set. Fold that\nnormalization into the initial frame preparation instead (on the staged\nbuffer for updates, directly on op->frames pre-registration for new\nops), so the installed frame is always atomically self-consistent.\n\nbcm_rx_handler()'s RX_RTR_FRAME check now takes a lock-protected\nsnapshot of op->flags before deciding whether to call bcm_can_tx(),\nbut does not hold the lock across that call.\n\nAlso take a lock-protected snapshot of the currframe in bcm_can_tx()\nto avoid partly overwrites by content updates in bcm_tx_setup().\nFinally check if a TX_RESET_MULTI_IDX/SETTIMER might have reset\nop->currframe between the two locked sections in bcm_can_tx().\n\nOmit calling hrtimer_forward() with zero interval in bcm_rx_thr_handler().\nkt_ival2 may have been concurrently

resolved:\n\ntipc: clear sock->sk on the failed-insert path in tipc_sk_create()\n\nWhen tipc_sk_create() fails to insert the new socket (tipc_sk_insert()\nreturns non-zero), its error path frees the sk with sk_free() but leaves\nsock->sk pointing at the freed object:\n\n\tif (tipc_sk_insert(tsk)) {\n\t\tsk_free(sk);\n\t\tpr_warn(\"Socket create failed; port number exhausted\\n\");\n\t\treturn -EINVAL;\n\t}\n\nThis is harmless for plain socket(): the syscall layer clears sock->ops\nbefore releasing, so tipc_release() is never called. It is not harmless\non the accept() path. tipc_accept() creates the pre-allocated child\nsocket with tipc_sk_create(net, new_sock, 0, kern); on failure it leaves\nnew_sock->sk dangling and new_sock->ops non-NULL, and do_accept() then\nfput()s the new file, so __sock_release() -> tipc_release() runs\nlock_sock(new_sock->sk) on the freed sk -- a use-after-free write of the\nsk_lock spinlock.\n\ntipc_release() already guards this exact \"failed accept() releases a\npre-allocated child\" case with \"if (sk == NULL) return 0;\", but the\nguard is bypassed because tipc_sk_create() left sock->sk non-NULL\n(dangling) rather than NULL.\n\nClear sock->sk on the failed-insert path so the existing tipc_release()\nNULL check fires and the use-after-free is avoided.\n\nThe tipc_sk_insert() failure is reached when the per-netns socket\nrhashtable hits its max_size (tsk_rht_params.max_size = 1048576, ~2M\nelements) -- i.e. once a netns holds ~2M TIPC sockets every insert\nreturns -E2BIG.\n\n BUG: KASAN: slab-use-after-free in lock_sock_nested (net/core/sock.c:3839)\n Write of size 8 at addr ffff8880047cdc38 by task init/1\n lock_sock_nested

resolved:\n\nbinfmt_misc: reject a flag character as the field delimiter\n\nThe registration string starts with a user chosen delimiter that\nseparates the individual fields. So that the field parsers terminate\neven on a truncated string create_entry() pads the buffer with that\nsame delimiter:\n\n\tmemset(buf + count, del, 8);\n\nMost fields are scanned for the delimiter with strchr()/scanarg() and\nhappily stop on the padding. The flags field is different: instead of\nscanning for the delimiter check_special_flags() consumes the flag\ncharacters 'P', 'O', 'C' and 'F' and stops at the first byte that is\nnone of them, relying on the trailing delimiter to end the scan.\n\nIf the delimiter is itself a flag character the padding no longer acts\nas a terminator. The scan swallows all eight padding bytes and keeps\nreading past the end of the allocation until it hits a byte that is\nnot a flag character. For example registering\n\n\tPaPEPPxPPiP\n\nwith 'P' as the delimiter (name \"a\", type extension, magic \"x\",\ninterpreter \"i\", empty flags) leaves the flag scan running off the end\nof the buffer. The registration is rejected in the end because the\nparser does not stop exactly at buf + count, but only after the out of\nbounds read has already happened. With an unlucky allocation layout the\nscan can walk into an unmapped page; under KASAN it is reported as a\nslab out of bounds read. binfmt_misc mounts are available to\nunprivileged users in a user namespace so the read is reachable without\nprivileges.\n\nReject a delimiter that is one of the flag characters up front. Such a\nregistration was always rejected anyway, only after the out of bounds\nread, so no valid registration string changes meaning.", "title": "Vulnerability description" } ], "product_status": {

state and\nbefore the structure is freed by callers like aggr_module_destroy().\n\nIf the timer callback (aggr_timeout) is executing when aggr_reset_state()\nis called, the callback will continue to access aggr_conn fields like\nrx_tid[] and stat[] which may be freed immediately after by\nkfree(aggr_info->aggr_conn) in aggr_module_destroy().\n\nAdditionally, the timer callback can re-arm itself via mod_timer() while\naggr_reset_state() is running, creating a more complex race condition.\n\nUse timer_delete_sync() instead to ensure any running timer callback\nhas completed before returning.",

resolved:\n\ninet: frags: strip GSO state from fragments before reassembly\n\nA virtio_net_hdr (tun/tap, or AF_PACKET with PACKET_VNET_HDR) can mark\nan IPv4 or IPv6 fragment as GSO; nothing relates gso_type to frag_off.\ninet_frag_reasm_prepare()/inet_frag_reasm_finish() keep the first\nfragment's skb as the head of the reassembled datagram, including its\nshinfo->gso_size/gso_type/gso_segs, and chain the remaining fragments\non frag_list with whatever linear/paged layout they arrived with.\n\nAfter ip_defrag() (ip_local_deliver(), nf_defrag_ipv4, ...) the\nreassembled skb therefore still claims to be GSO (SKB_GSO_DODGY), and\nthe next software segmentation point - udp_rcv_segment() on local\ndelivery, validate_xmit_skb(), or the ip_finish_output_gso() slow\npath - hands it to skb_segment(). skb_segment()'s frag_list walk\nassumes GRO-shaped input and hits one of its BUG_ON()s. Two writes to\na tap by an unprivileged user in its own userns are enough:\n\n kernel BUG at net/core/skbuff.c:4899!\n Oops: invalid opcode: 0000 [#1] SMP KASAN NOPTI\n CPU: 0 UID: 1000 PID: 82 Comm: poc Not tainted 7.2.0-pentest+ #2\n RIP: 0010:skb_segment+0x20ca/0x48b0\n Call Trace:\n \n __udp_gso_segment+0x29a/0x27d0\n udp4_ufo_fragment+0x458/0x6c0\n inet_gso_segment+0x429/0x1340\n skb_mac_gso_segment+0x233/0x4f0\n __skb_gso_segment+0x308/0x660\n udp_queue_rcv_skb+0x440/0xad0\n udp_unicast_rcv_skb+0xc7/0x2c0\n udp_rcv+0x16ce/0x2260\n ip_protocol_deliver_rcu+0x197/0x2d0\n ip_local_deliver+0x430/0x690\n ip_rcv+0x16f/0x1f0\n __netif_receive_skb_one_core+0x15e/0x1c0\n __netif_receive_skb+0x1e/0x110\n netif_receive_skb+0xf6/0x5c0\n tun_rx_batched.isra.0+0x3ab/0x790\n tun_get_user+0x17c3/0x3550\n tun_chr_write_iter+0xba/0x1b0\n vfs_write+0x646/0x1130\n \n Kernel panic - not syncing: Fatal exception in interrupt\n\nThis runs with BH disabled, so it is a panic rather than an oops. The\nsame is reachable with CAP_NET_RAW in a netns where a defrag point\nprecedes a GSO point, and from a guest whose VMM forwards\nvirtio_net_hdr to a tap. The SKB_GSO_DODGY frag_list checks added by\ncommit 3dcbdb134f32 (\"net: gso: Fix skb_segment splat when splitting\ngso_size mangled skb having linear-headed frag_list\") and by\ncommit 9e4b7a99a03a (\"net: gso: fix panic on frag_list with mixed head\nalloc types\") do not cover it: page-backed heads skip them, and kmalloc\nheads skip them when gso_size == skb_headlen(head), which the sender\ncontrols.\n\nAn skb entering a frag queue is an IP fragment by definition and\ncannot legitimately carry GSO state: GRO does not merge fragments and\nthe stack segments before it fragments, so only untrusted sources are\naffected. This has been reachable since\ncommit f43798c27684 (\"tun: Allow GSO using virtio_net_hdr\"), the first\npath that let userspace attach GSO metadata to an IP fragment. Reset\nthe GSO fields of every fragment as it is queued, in\ninet_frag_queue_insert(), which IPv4, IPv6, nf_conntrack_reasm and\n6lowpan reassembly share; then neither the head nor the frag_list\nmembers of the reassembled skb carry them (the members matter too:\nthe ip_do_fragment()/ip6_fragment() fast paths send them out as they\nare). The head may remain CHECKSUM_PARTIAL; that is already accepted\non receive and resolved by skb_checksum_help() in\nip_do_fragment()/ip6_fragment() on forward.\n\nTested on top of net.git (dc4b95b8fee9), x86_64: the tap reproducer\nabove, two further IPv4 frag_list geometries that reach\nBUG_ON(i >= nfrags) and BUG_ON(!list_skb->head_frag), and an IPv6\nfragment-header variant (udp6_ufo_fragment()) each panic the unpatched\nkernel; with this patch all four datagrams are delivered intact and\nnothing is logged.", "title": "Vulnerability description" } ], "product_status": {

sizeof(*res);\n\nwithout first checking that buffer_len is at least sizeof(struct\nwilc_assoc_resp) (6 bytes). buffer_len is the length reported for a\nreceived association response (host_int_parse_assoc_resp_info() passes\nhif_drv->assoc_resp / assoc_resp_info_len straight in) and must be\nvalidated before the driver accesses the fixed header.\n\nFor a frame shorter than the 6-byte fixed header, the subtraction wraps.\nFor a four-byte response the result is truncated to a u16 ies_len of\n65534, so kmemdup() then attempts to copy 65534 bytes starting at\nbuffer + sizeof(*res), beyond the valid association-response data\n(CWE-125). A response shorter than four bytes can also cause an\nout-of-bounds read of res->status_code at offsets 2 and 3.\n\nReject frames too short to hold the fixed header before touching the\nheader or computing ies_len. Also set the connection status to a failure\non this path: the caller falls through to a\n\"conn_info->status == WLAN_STATUS_SUCCESS\" check after the parser\nreturns, so leaving the status untouched

resolved:\n\nsctp: avoid auth_enable sysctl UAF during netns teardown\n\nproc_sctp_do_auth() updates the SCTP control socket after changing\nnet.sctp.auth_enable. The handler gets the per-net SCTP state from\nctl->data, so an already opened sysctl file can still target a network\nnamespace while that namespace is being torn down.\n\nSCTP previously registered its per-net sysctls from sctp_defaults_init(),\nwhile the control socket is created later from sctp_ctrlsock_init(). This\nexposed a window during initialization where auth_enable was writable\nbefore net->sctp.ctl_sock existed, and a teardown window where auth_enable\nstayed writable after inet_ctl_sock_destroy() had released the control\nsocket.\n\nMove the per-net SCTP sysctl registration into sctp_ctrlsock_init() after\nsctp_ctl_sock_init() succeeds, and unregister the sysctl table before\ndestroying the control socket in sctp_ctrlsock_exit(). If sysctl\nregistration fails after the control socket was created, destroy the\ncontrol socket in the same init path.\n\nMake sctp_sysctl_net_unregister() tolerate a missing header and clear the\nsaved pointer so init-error and exit paths can safely share the unregister\nhelper.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

still creates a trace_event_file pointing to it.\nIf module loading subsequently fails and module memory is freed, tracing\nstate retains a stale trace_event_call pointer in trace_event_file,\nleading to a use-after-free when tracefs or tracing subsystem operations\nare later executed.\n\nFix this by checking the return value of __register_event() and only\ncalling __add_event_to_tracers() if event

resolved:\n\nmedia: msi2500: Return queued buffers on start_streaming() failure\n\nThe vb2 framework hands buffers to the driver via buf_queue() before\ncalling start_streaming(). If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nmsi2500_start_streaming() had five error paths that all hit this trap\nand were further tangled by ret-overwriting between calls:\n\n - -ENODEV when the USB device was already disconnected\n - -ERESTARTSYS when mutex_lock_interruptible() was interrupted\n - msi2500_set_usb_adc() failure: ret was silently overwritten by\n the next call (msi2500_isoc_init), so the error was lost entirely\n - msi2500_isoc_init() failure: cleanup_queued_bufs was called, but\n the function then fell through to msi2500_ctrl_msg() and again\n masked the original error by overwriting ret\n - msi2500_ctrl_msg(CMD_START_STREAMING) failure: no cleanup at all,\n leaving isoc URBs submitted with no way for the driver to consume\n them\n\nConsolidate the error paths into a small goto chain. Every failure\nnow stops the function, drains the queued-buffer list, and returns\nthe real error code. The ctrl_msg failure path also rolls back the\npreceding msi2500_isoc_init() via msi2500_isoc_cleanup() before\nunlocking and draining.\n\nThe cleanup helper takes a vb2_buffer_state argument so that the\nstart_streaming error paths can pass VB2_BUF_STATE_QUEUED (as\nexpected by userspace on start_streaming failure) while stop_streaming\nkeeps its existing VB2_BUF_STATE_ERROR semantics.\n\nThis

resolved:\n\ncdrom: fix stack out-of-bounds read in CDROMVOLCTRL\n\nmmc_ioctl_cdrom_volume() first reads the audio control mode page into a\n32-byte stack buffer with cgc->buflen set to 24. If the device reports a\nblock descriptor, the function increases cgc->buflen to include that\ndescriptor and reads the page again.\n\nFor CDROMVOLCTRL, the function then builds a MODE SELECT parameter list\nby moving cgc->buffer forward by offset - 8 bytes. This drops the block\ndescriptor from the outgoing payload and leaves a new 8-byte mode\nparameter header in front of the audio control page. However, cgc->buflen\nis left unchanged.\n\nWith a standard 8-byte block descriptor, cgc->buffer points at buffer + 8\nbut cgc->buflen remains 32. cdrom_mode_select() therefore asks the low\nlevel packet path to write 32 bytes from that adjusted pointer, reading 8\nbytes past the end of the 32-byte stack buffer.\n\nThis is not hit by CDROMVOLREAD, and CDROMVOLCTRL only triggers it on\ndrives that return a non-zero block descriptor length, which helps explain\nwhy it has gone unnoticed. The overread is also sent to the device as\nextra MODE SELECT payload, so it may not produce an obvious local failure.\n\nReduce cgc->buflen by the same amount as the buffer pointer adjustment so\nthe MODE SELECT transfer covers only the intended parameter list.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

`parport_interrupt()` in the \"comedi_parport\" driver, but it\ndoes not currently have a C reproducer for the problem. It's\nprobably due to a premature interrupt for one of two reasons:\n\n1. The driver sets up the interrupt handler before the comedi subdevices\n used by the interrupt handler have been allocated, but does not\n disable the interrupt in the parallel port's CTRL register first.\n2. The driver uses a user-supplied I/O port base address which Syzbot\n would have supplied, but it might not be backed by real parallel port\n hardware.\n\nChange the initialization order in the driver's comedi \"attach\" handler\n(`parport_attach()`) so that the hardware registers are initialized\nbefore the interrupt handler is requested. This should prevent\npremature interrupts occurring for real hardware.\n\nAlso add a test to the interrupt handler to ensure the comedi device is\nfully attached and return early if it isn't.",

struct sctp_paramhdr\nfollowed by N HMAC identifiers.\n\nHowever, the array size was calculated using an extra 2 bytes instead of\nsizeof(struct sctp_paramhdr), which is 4 bytes. When four HMAC identifiers\nare configured, the HMAC-ALGO parameter stored in the endpoint is larger\nthan the auth_hmacs buffer in the cookie.\n\nAs a result, sctp_association_init() copies beyond the end of auth_hmacs\nwhen initializing the association, corrupting the adjacent auth_chunks\nfield. This can lead to an invalid HMAC identifier being accepted and later\ncause an out-of-bounds read in sctp_auth_get_hmac().\n\nFix the array size calculation by including the full SCTP parameter

and calls carl9170_restart()\nbut then falls through to memcpy(ar->readbuf, buffer + 4, len - 4).\nSince len comes from the firmware and can exceed ar->readlen, this\ncopies more data than the readbuf

checking a lower bound, then\nset udata_offset to a fixed non-zero value and pass both to a reply\ncallback. The callback bounds-checks the copy with\n\n if ((udata_len - udata_offset) < len)\n\nBoth fields are u32, so a udata_len smaller than udata_offset makes the\nsubtraction wrap and the check pass, and the following memcpy() writes\npast the allocation. A udata_len of 0 also yields ZERO_SIZE_PTR from\nkzalloc(), which the existing NULL check does not catch.\n\nReject buffers smaller than udata_offset before allocating, so the\ncallback subtraction

sk_dst_cache with\nrcu_dereference_protected(), stores NULL and dst_release()s the old dst.\nThat is only safe if no other thread modifies sk_dst_cache concurrently.\n\nFor a connected UDP socket that does not hold: the transmit fast path\n(udp_sendmsg -> sk_dst_check -> sk_dst_reset) resets the cache locklessly\nwith an atomic xchg().

resolved:\n\nIB/mad: Drop unmatched RMPP responses before reassembly\n\nKernel-handled RMPP receive processing starts reassembly for active\nDATA responses before the response is matched to an outstanding send.\nThe normal match happens later, after ib_process_rmpp_recv_wc() has\neither assembled a complete message or consumed the segment.\n\nThat ordering lets an unsolicited response that routes to a kernel\nRMPP agent by the high TID bits allocate or extend RMPP receive state\nbefore the full TID and source address are checked against a real\nrequest. A reordered burst can therefore reach the receive-side\ninsertion path even though the response would not match any send.\n\nFor kernel-handled RMPP DATA responses, require the existing\nib_find_send_mad() match before entering RMPP reassembly. The matcher\nalready checks the full TID, management class and source address/GID\nagainst the agent wait, backlog and in-flight send lists. If there is\nno match, drop the response without creating RMPP state.\n\nThis leaves the RMPP window behavior unchanged and only rejects\nresponses that have no corresponding request.", "title":

one.\n\nrinfo->length is the ND option length in units of 8 octets and it\n*includes* the 8-byte option header, so an option carrying N bytes of\nprefix has length == 1 + N/8. RFC 4191 section 2.3 requires length 3\nwhen Prefix Length is greater than 64, and 2 or 3 when it is greater\nthan 0. The code accepts length >= 2 and length >= 1 respectively.\n\nipv6_addr_prefix() then copies prefix_len/8 bytes out of rinfo->prefix,\nso a Router Advertisement with (prefix_len=128, length=2) or\n(prefix_len=64, length=1) makes the kernel read up to 8 bytes past the\nend of the option. Those bytes end up in the prefix of the route that\ngets installed, so they are visible to userspace:\n\n # RA with a Route Information option (prefix_len=128, length=2)\n # followed by a source

resolved:\n\ngpio: pch: use raw_spinlock_t for the register lock\n\npch_irq_type() is registered as the irq_chip .irq_set_type callback and\ntakes chip->spinlock with spin_lock_irqsave(). This callback is reached\nfrom __setup_irq() -> __irq_set_trigger() -> chip->irq_set_type() while\nthe caller holds desc->lock, a raw_spinlock_t, with hardirqs disabled.\nThat context is not sleepable, but on PREEMPT_RT a regular spinlock_t is\nan rtmutex-backed sleeping lock, so acquiring it there is invalid.\n\nThis was confirmed on a PREEMPT_RT kernel with lockdep\n(PROVE_RAW_LOCK_NESTING and DEBUG_ATOMIC_SLEEP). A grounded PoC mirrored\npch_irq_type()'s locking and drove it through the real genirq carrier\nirq_set_irq_type() -> __irq_set_trigger() -> chip->irq_set_type(), i.e.\nthe same __irq_set_trigger() edge that __setup_irq() takes for a\nrequested IRQ. With the original spin_lock_irqsave() edge lockdep\nreported an invalid wait context, immediately followed by:\n\n BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48\n in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 95, name: insmod\n hardirqs last disabled at (3784): _raw_spin_lock_irqsave+0x4f/0x60\n rt_spin_lock+0x3a/0x1c0\n repro_irq_set_type+0x64/0xa0 [pch_repro]\n __irq_set_trigger+0x69/0x140\n irq_set_irq_type+0x78/0xd0\n\nSwitching the mirrored lock to raw_spinlock_t made both splats go away.\n\nConvert the register lock to raw_spinlock_t. The same lock also\nserializes the GPIO direction/value callbacks and the suspend/resume\nregister save/restore, but all of those critical sections only perform\nMMIO register accesses (ioread32()/iowrite32()) and\nirq_set_handler_locked(); none of them contain sleepable operations.\nKeeping this register lock non-sleeping is therefore appropriate for the\nirqchip callbacks and does not change the GPIO-side locking contract.\n\nThis is the same class of issue and fix as recently addressed for other\nGPIO controllers, e.g. commit 286533cb14a3 (\"gpio: sch: use raw_spinlock_t\nin the irq startup path\") and commit 90f0109019e6 (\"gpio: eic-sprd: use\nraw_spinlock_t in the irq startup path\").", "title": "Vulnerability description" } ], "product_status": { "fixed": [

can be called, which may\nreallocate skb->head.\n\nIn this case, returning to vxlan_xmit() leaves the cached eth pointer pointing to\nfreed memory, leading to a use-after-free when dereferencing

But if cp_init()\nfails, and cp->initialized is not enabled, the same routine cannot be\nused to free all the memory.\n\nAn attempt to address this exists in ccwchain_handle_ccw(), where a\nsingle call to ccwchain_free() is made for the currently-processed\nCCW segment. But this will leak other segments (created as a result\nof a Transfer in Channel) that had been allocated as part of the same\nchannel program.\n\nAddress this by performing the cleanup outside of the

resolved:\n\nRDMA/rxe: Fix a use-after-free problem in rxe_mmap\n\nrxe_mmap() removes a rxe_mmap_info struct from the pending_mmaps list\nand releases pending_lock while the struct's kref is still at 1:\n\n list_del_init(&ip->pending_mmaps);\n spin_unlock_bh(&rxe->pending_lock); /* ref == 1, no lock held */\n ret = remap_vmalloc_range(vma, ip->obj, 0); /* walks PTEs */\n [...]\n rxe_vma_open(vma); /* kref_get, ref → 2 */\n remap_vmalloc_range_partial() walks PTEs without any lock.\n\nA concurrent DESTROY_CQ ioctl on another CPU calls:\n\n kref_put(&q->ip->ref, rxe_mmap_release) /* ref 1→0 */\n vfree(ip->obj) /* clears vmalloc PTEs mid-walk */\n kfree(ip) /* frees rxe_mmap_info */\n\nThis yields:\n\n 1. Kernel crash, vmalloc_to_page() returns NULL when vfree wins the\n per-PTE race -> vm_insert_page(NULL) → GPF in validate_page_before_insert\n\n 2. Page UAF, vmalloc_to_page() reads a stale PTE before vfree clears\n it. User VMA holds a PTE to a free'd page which might eventually get\n reallocated later by vmalloc which allows the attacker to get a clean\n page-level UAF.\n\n It is worth noting that even though a page-level UAF is possible given\n the strong primitive, it is statistically very difficult to achieve\n given the very short time window (after the last insert_page and before\n the kref_get).\n\nThe call trace are as below:\n\n Oops: general protection fault, probably for non-canonical address 0xdffffc0000000001: 0000 [#1] SMP KASAN NOPTI\n KASAN: null-ptr-deref in range

authlen;\n\nwhere datalen is the number of bytes after the MAC header and authlen\n(4, 8 or 16) is the length of the authentication tag. Nothing verifies\nthat the frame actually carries at least authlen payload bytes. A\nsecured frame whose payload is shorter than the tag makes\ndatalen - authlen negative; assoclen is then passed to\naead_request_set_ad() as an unsigned value close to 4 GiB, so\ncrypto_aead_decrypt() walks far off the end of the scatterlist that\nonly spans the real frame.\n\nThe frame is fully attacker-controlled and reaches this path from any\nIEEE 802.15.4 peer in radio range. Reject frames whose payload is\nshorter than the authentication tag before the subtraction.\n\nDynamically reproduced on a KASAN kernel as a general-protection-fault\nin the AEAD scatterwalk, and the

In that window the active slave can change under RTNL\n(RTM_DELLINK -> __bond_release_one() -> bond_alb_handle_active_change()),\nwhich already drops the promiscuity and clears primary_is_promisc.

resolved:\n\nbinfmt_misc: restore write access when removing an entry\n\nRegistering an entry with the MISC_FMT_OPEN_FILE flag opens the\ninterpreter via open_exec() which denies write access to it for as\nlong as the entry exists. Removing the entry closes the interpreter\nfile via filp_close() but never restores write access, leaving the\ninode's i_writecount permanently negative. Opening the interpreter\nfor writing keeps failing with ETXTBSY long after the entry is gone\nuntil the inode is evicted from the inode cache.\n\nCommit 90f601b497d7 (\"binfmt_misc: restore write access before\nclosing files opened by open_exec()\") fixed the same imbalance in the\nerror path of bm_register_write() but the actual removal path has\nbeen leaking the write denial since the introduction of the flag.\n\nRestore write access in put_binfmt_handler() before closing the\ninterpreter file.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nKVM: x86/mmu: Fix use-after-free on vendor module reload\n\nmmu_destroy_caches() destroys pte_list_desc_cache and\nmmu_page_header_cache, but leaves both pointers unchanged. The pointers\nlive in kvm.ko, and therefore survive when a vendor module is unloaded\nwhile kvm.ko remains loaded.\n\nIf creation of pte_list_desc_cache fails during a subsequent vendor\nmodule load, its assignment sets pte_list_desc_cache to NULL and the\nerror path calls mmu_destroy_caches(). mmu_page_header_cache still\npoints to the cache destroyed during the preceding vendor module\nunload. Passing that stale pointer to kmem_cache_destroy() causes a\nslab use-after-free.\n\nReproduce the issue on a v7.1.3 kernel with CONFIG_KASAN=y,\nCONFIG_KASAN_GENERIC=y, CONFIG_KVM=m, and CONFIG_KVM_INTEL=m. A\none-shot test hook forces pte_list_desc_cache to NULL on the second\ninvocation of kvm_mmu_vendor_module_init():\n\n 1. Load kvm.ko and kvm-intel.ko, creating both caches.\n 2. Unload only kvm_intel, leaving kvm.ko loaded.\n 3. Reload kvm_intel and force initialization through the -ENOMEM path.\n\nKASAN reports:\n\n BUG: KASAN: slab-use-after-free in\n kvm_mmu_vendor_module_init+0x5b/0x170 [kvm]\n ...\n

its socket. The connection\nis embedded in the socket, and its registration reference protects it only\nwhile the connection remains in the tree.\n\nA concurrent close can unregister the connection and drop that reference,\nfreeing the socket before the termination worker reaches sock_hold().\n\nThe race is reachable when close overlaps link group termination.\nLocal stress testing reproduced the

Worse, it returns without a\nNACK+STOP: the next receive cycle has already started, so the target\nkeeps holding SDA and the bus stays stuck until a power cycle for\nthis i2c controller.\n\nReading I2DR to obtain the count likewise arms the next byte on the\ncount > I2C_SMBUS_BLOCK_MAX path, which also returned -EPROTO directly\nand left the bus held.\n\nHandle both: NACK the in-flight dummy byte (TXAK) and extend msgs->len so\nthe existing last-byte handling emits STOP; the dummy byte is discarded.\nA count of 0 is a valid empty block read; a count above\nI2C_SMBUS_BLOCK_MAX is still reported as -EPROTO, but only after the bus\nhas been released.\n\nThe interrupt-driven path has the same flaw from a later commit and is\nfixed separately, as it carries a different Fixes: tag and

Two RTM_NEWTFILTER requests on different CPUs, each\nadding a flower filter with a police action carrying the same rate, then\nrace on qdisc_rtab_list and on the non-atomic refcnt, leading to a\nuse-after-free / double-free of the kmalloc-2k struct qdisc_rate_table.\nqdisc_rtab_list is a single global (not per-netns), so the corrupted\nobject is shared system-wide.\n\n BUG: KASAN: slab-use-after-free in qdisc_put_rtab+0x12f/0x160\n qdisc_put_rtab+0x12f/0x160\n tcf_police_init+0xda9/0x1590\n tcf_action_init_1+0x460/0x6b0\n tcf_action_init+0x439/0xa40\n tcf_exts_validate_ex+0x42d/0x550\n fl_change+0xddd/0x7da0\n tc_new_tfilter+0xaa7/0x2420\n rtnetlink_rcv_msg+0x95e/0xe90\n which belongs to the cache kmalloc-2k of size 2048\n\nProtect qdisc_rtab_list and the refcount with a dedicated spinlock.

field. For a partial IPv6\naddress match (field_len = 16, priv_len = 1) that shift is 1 << 120, which\nis undefined on the 32-bit int operand. It also trims only one word, so\nthe remaining words stay 0xffffffff (and when priv_len is a multiple of 4\nthe trim is skipped entirely), leaving the mask covering more bytes than\nthe rule matches.\n\n UBSAN: shift-out-of-bounds in net/netfilter/nft_payload.c:278:20\n shift exponent 120 is too large for 32-bit type 'int'\n ...\n\nThe match is byte-granular and struct nft_data is zero-initialised, so the\ncorrect mask is simply the first priv_len bytes set to 0xff.

resolved:\n\nrds: drop incoming messages that cross network namespace boundaries\n\nrds_find_bound() looks up the destination socket using a global\nrhashtable keyed solely on (addr, port, scope_id). Network namespaces\nare not part of the key, so a sender in netns A can deliver an incoming\nmessage (inc) to a socket that lives in a different netns B.\n\nWhen this happens, inc->i_conn points to an rds_connection whose c_net\nis netns A, but the receiving rs lives in netns B. Once the child\nprocess that created netns A exits, cleanup_net() calls\nrds_loop_exit_net() -> rds_loop_kill_conns() -> rds_conn_destroy(),\nfreeing that connection. If the survivor socket in netns B still holds\nthe inc, any subsequent dereference of inc->i_conn is a use-after-free.\n\nThere are two dangerous sites in rds_clear_recv_queue():\n 1. inc->i_conn->c_lcong (offset 88 of freed rds_connection, size 200)\n read via rds_recv_rcvbuf_delta() -- confirmed by KASAN.\n 2. inc->i_conn->c_trans->inc_free(inc) (function pointer at offset 80)\n called via rds_inc_put() when the inc refcount reaches zero -- same\n race window, potential call-through-freed-object primitive.\n\nThe bug is reachable from unprivileged user namespaces\n(CLONE_NEWUSER + CLONE_NEWNET), available since Linux 3.8.\n\nFix this by rejecting the delivery in rds_recv_incoming() when the\nsocket returned by rds_find_bound() belongs to a different network\nnamespace than the connection that carried the message. Use the\nexisting rds_conn_net() / sock_net() helpers and net_eq() for the\ncomparison.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

skb in its gso_skb; taprio_dequeue_from_txq()\nthen takes the packet with a direct child ->dequeue() call, which ignores\nthat stash, orphans the peeked skb and desyncs the child's qlen/backlog.\nWith a qfq child this re-enters the child on an emptied list and\ndereferences NULL, panicking the kernel from softirq on ordinary egress.\n\nTake the packet through qdisc_dequeue_peeked(), as sch_red and sch_sfb\nnow do. The helper returns the child's stashed skb first and is a no-op\nwhen there is none, so a work-conserving child is unaffected and the\ngated path now consumes the skb whose length was charged to the

through po->prot_hook.func\nafter releasing that lock. packet_poll() and packet_recvmsg() can then\nrun the pressure clearing path after the ring has been cleared while\nstill seeing tpacket_rcv, causing __packet_rcv_has_room() to dereference\nstale or NULL ring storage.\n\nMove the existing receive hook assignment into the same\nsk_receive_queue.lock section as the ring state update. Keep the\nassignment otherwise unchanged, including on TX ring reconfiguration, to\navoid adding behavior changes that are not required for the fix.\n\nSerialize packet_recvmsg() pressure clearing with the same queue lock\nonly after PACKET_SOCK_PRESSURE has been observed. If the flag is clear\nand the socket has moved away from tpacket_rcv, packet_set_ring() has\nalready detached the socket and waited for synchronize_net(), so no new\npacket input can set the flag

wildcard filter list, so\nbcm_rx_handler() can run concurrently on different CPUs for frames\narriving on different net devices.\n\nop->rx_stamp and op->rx_ifindex were written before bcm_rx_update_lock was\ntaken, allowing concurrent writers to race each other - including a torn\nstore of the 64-bit rx_stamp on 32-bit platforms.\n\nBeyond a torn store bcm_send_to_user() must report the timestamp/ifindex\nof the very same frame whose content it is delivering. So the assignment\nis placed in the same unbroken bcm_rx_update_lock section as the content\ncomparison.\n\nAs a side effect, the RTR-request frame feature (which never reach\nbcm_send_to_user()) no

resolved:\n\nmedia: v4l2-fwnode: Fix subdev owner overwritten in v4l2_async_register_subdev_sensor()\n\nThe v4l2 helper v4l2_async_register_subdev_sensor() calls\nv4l2_async_register_subdev(), which is a macro that expands to\n__v4l2_async_register_subdev(sd,THIS_MODULE). Since the macro is expanded\ninside v4l2-fwnode.c, THIS_MODULE resolves to the v4l2-fwnode module\nrather than the sensor driver module that originally set sd->owner. When\nv4l2-fwnode is built-in, THIS_MODULE evaluates to NULL, which then\noverwrites the sensor driver's owner with NULL.\n\nThis causes the problem that the sensor module's reference count is never\nincremented during async registration, so the module can be removed while\nthe subdevice is still in use by a notifier (e.g., a CSI-2 receiver\nbridge driver).\n\nFix this by renaming v4l2_async_register_subdev_sensor() to\n__v4l2_async_register_subdev_sensor() with an added explicit module\nargument and introducing a wrapper macro:\n #define v4l2_async_register_subdev_sensor(sd) \\\n __v4l2_async_register_subdev_sensor(sd, THIS_MODULE)\n\nThis ensures the sensor driver module is properly referenced even when\nthe sensor driver does not init the owner field before calling\nv4l2_async_register_subdev_sensor() and prevents premature module removal.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

an incoming qentry into the local LLC flow\nwithout first checking whether a qentry is already pending. If a malicious or\nbuggy peer sends a second CONFIRM_LINK or ADD_LINK_CONT request while a flow is\nactive and flow->qentry is already set, smc_llc_flow_qentry_set() overwrites the\npointer without freeing the previous allocation, leaking one kmalloc-96 object\nper spurious message.\n\nThe sibling SMC_LLC_DELETE_LINK branch already has the correct !flow->qentry\nguard. Apply the same guard to the CONFIRM_LINK/ADD_LINK_CONT branch so that a\nduplicate message when qentry is already occupied falls through to break and is\nfreed by the kfree(qentry) at the out: label, rather than silently leaking the\nexisting allocation.\n\nThe response direction (smc_llc_rx_response()) is unaffected: it already guards\nwith flow->qentry at the equivalent site and drops duplicate responses\ncorrectly.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

already\ntorn down its registration (op->rx_reg_dev == NULL). This silently\ndid not re-enable frame delivery for that updated filter. bcm_rx_setup()\nnow re-registers in that case, while leaving rx_ops with ifindex = 0\n(all CAN devices) which never carry a tracked rx_reg_dev registered as-is.\n\nTX: bcm_notify() only handled bo->rx_ops on NETDEV_UNREGISTER, leaving\ntx_ops with an active cyclic transmission re-arming its hrtimer\nindefinitely to execute bcm_tx_timeout_handler(). Cancelling the hrtimer\nprevents the runaway timer and any injection into a later reused ifindex,\nsince nothing else calls bcm_can_tx() for the op until an explicit\nTX_SETUP update re-arms it.\n\nUnlike bcm_rx_unreg(), which clears the tracked rx_reg_dev for rx_ops,\nthe ifindex is intentionally left unchanged for tx_ops. bcm_tx_setup()\nalways rejects ifindex 0, so clearing it would

resolved:\n\nnet/packet: avoid fanout hook re-registration after unregister\n\npacket_set_ring() temporarily detaches a socket from packet delivery while\nreconfiguring its ring. It records the previous running state, clears\npo->num, unregisters the protocol hook when needed, drops po->bind_lock,\nand later restores po->num and re-registers the hook from the saved\nwas_running value.\n\nThat unlocked window can race with NETDEV_UNREGISTER. The notifier can\nobserve the socket as not running, skip __unregister_prot_hook(), and\ninvalidate the per-socket binding by setting po->ifindex to -1 and clearing\npo->prot_hook.dev. A one-member fanout group can still retain its shared\nfanout hook device pointer. When packet_set_ring() resumes, re-registering\nsolely from the stale was_running state can re-add the fanout hook after\nthe device has been unregistered.\n\nTreat po->ifindex == -1 as an invalidated binding after reacquiring\npo->bind_lock. This is distinct from ifindex 0, the normal\nunbound/wildcard state: ifindex -1 marks an existing device binding that\nwas invalidated when the device was unregistered. Restore po->num as\nbefore, but do not re-register the hook if device unregister already\ndetached the socket.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nxfs: bounds-check buffer log item's dirty bitmap\n\nxlog_recover_do_reg_buffer() replays each dirty region described by a\nbuffer log item's bitmap into the buffer read for that item:\n\n\tmemcpy(xfs_buf_offset(bp, (uint)bit << XFS_BLF_SHIFT),\n\t\titem->ri_buf[i].iov_base,\n\t\tnbits << XFS_BLF_SHIFT);\n\nThe destination offset (bit/nbits, from the logged dirty bitmap) and the\nbuffer size (from the logged blf_len) are both attacker-controlled and\notherwise unrelated, yet the only thing bounding the copy is an ASSERT(),\nwhich compiles away on production kernels. A crafted image logging a\nsmall blf_len together with a bitmap bit past the end of that buffer\ndrives the memcpy() past the buffer's allocation, corrupting adjacent\nkernel heap during mount-time log recovery. This is reachable by anyone\nwho can get a crafted image mounted -- the malicious-filesystem threat\nmodel XFS already guards against elsewhere.\n\nTurn the ASSERT() into a real XFS_IS_CORRUPT() check that aborts recovery\nof the buffer with -EFSCORRUPTED, consistent with the validate-and-fail\nidiom already used in xlog_recover_do_inode_buffer() and\nxfs_dquot_item_recover.c. xlog_recover_do_reg_buffer() therefore becomes\nSTATIC int and its three callers propagate the error.\n\nFound and confirmed with KASAN on a CONFIG_XFS_DEBUG=n build: the crafted\nimage trips a slab-out-of-bounds write before this change and fails\nrecovery cleanly with -EFSCORRUPTED after it.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\ncan: bcm: defer rx_op deallocation to workqueue to fix thrtimer UAF\n\nCommit f1b4e32aca08 (\"can: bcm: use call_rcu() instead of costly\nsynchronize_rcu()\") replaced synchronize_rcu() in bcm_delete_rx_op()\nwith call_rcu() and introduced the RX_NO_AUTOTIMER flag.\n\nHowever, this flag check was omitted for thrtimer in the packet rx\nfast-path. During BCM RX operation teardown, a concurrent RCU reader\n(bcm_rx_handler) can race and re-arm thrtimer via\nbcm_rx_update_and_send() after call_rcu() has been scheduled. Once\nthe RCU grace period elapses, bcm_op is freed. The subsequently\nfiring thrtimer then dereferences the deallocated op, causing a UAF.\n\nAdding flag checks to the rx fast-path (bcm_rx_update_and_send) does not\nfully close the TOCTOU race and introduces latency for every CAN frame.\nConversely, calling hrtimer_cancel() directly inside the RCU callback\n(softirq context) is fatal as hrtimer_cancel() can sleep, triggering\na \"scheduling while atomic\" panic.\n\nResolve this by deferring the timer cancellation and memory free to a\ndedicated unbound workqueue (bcm_wq). The RCU callback now queues a\nwork item to bcm_wq, which safely cancels both timers and deallocates\nmemory in sleepable process context. A dedicated workqueue is used to\nprevent system-wide WQ saturation and is cleanly flushed/destroyed\non module unload to avoid rmmod page faults.\n\nSince the deferred work can now outlive the calling context by an\nunbounded amount, also take a reference on op->sk when it is assigned\nand drop it only once the deferred work has cancelled both timers, so a\nsocket can no longer be freed out from under a still-armed timer whose\ncallback (bcm_send_to_user()) dereferences op->sk.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

malicious host can supply a large offset that overflows the signed\nndp_index, making it negative. Because ndp_index is compared against\nunsigned bounds, this negative value bypasses sanity checks and leads\nto an out-of-bounds read when calculating the address of the NDP\nblock (ntb_ptr +

Descriptor's metadata. The ID is\nextracted using the helper function cppi5_desc_get_tags_ids() which fills\nin the 16-bit Source Tag into the 'port_id' variable. However, it is only\nthe lower 8-bits of the 16-bit Source Tag that represent the MAC Port ID,\nwhile the upper 8-bits are Hardware-Reserved and carry an arbitrary value.\nWith the existing logic, sporadic kernel crash is observed due to the\nsubsequent driver code accessing out-of-bound memory because of an invalid\nport_id.\n\nHence, fix the port_id extraction logic to use only the lower

backlogged. The parsing code contains a\nWARN_ON(1) which can be triggered by a malformed IP header in certain\ncases. Depending on the system configuration, this leads either to\neither spamming dmesg with warnings, or a panic if panic_on_warn is set.\n\nThe code already correctly skips the offending packet in the branch that\ntriggers the warning, so the WARN_ON itself doesn't really serve any\npurpose.

RCU keeps the memory accessible through the attempted\nreference acquisition, and a successful increment pins the object for\nthe caller.\n\nAn independent run on the exact unpatched 6f5156d7a31a (v7.2-rc3)\nkernel reproduced the invalid reference acquisition as UID 1000:\n\n refcount_t: addition on 0; use-after-free.\n ip6_mc_source+0xef4/0x17e0\n\nIt was followed by the corresponding reference underflow in\nip6_mc_source(). The supplied trace from the same unpatched revision\nadditionally shows the access after the RCU read-side section ends:\n\n BUG: KASAN: slab-use-after-free in mutex_lock+0x76/0xe0\n Write of size 8

resolved:\n\nceph: fix hanging __ceph_get_caps() with stale mds_wanted\n\nA reader can hang forever in __ceph_get_caps() when the client no\nlonger holds `FILE_RD`, but local cap state still says that the\ncapability is already wanted (via `mds_wanted`).\n\nOne way to trigger this is through MDS cap revocation. If another\nclient performs a conflicting operation, the MDS can revoke `FILE_RD`\nfrom the reader; the next read then has to reacquire `FILE_RD`. If\nthe cap update that should request `FILE_RD` never reaches the MDS\nafter `cap->mds_wanted` was raised, the reader is left holding only\nnon-file caps while local `mds_wanted` still includes the file read\ncaps.\n\nIn that state, try_get_cap_refs() sees `need <= mds_wanted` and\nreturns 0, so __ceph_get_caps() just waits on `i_cap_wq`. If the cap\nupdate that was supposed to request `FILE_RD never reaches the MDS\nafter `cap->mds_wanted was` raised, no further request is sent and the\nwaiter can sleep indefinitely until unrelated cap traffic happens to\nwake it up.\n\nThe ordering issue is that `cap->mds_wanted` is updated in\n__prep_cap() before the `CEPH_MSG_CLIENT_CAPS message` is actually\nqueued for send. That makes one field serve two different meanings at\nonce: what this client wants, and what the client believes the MDS\nalready knows it wants.\n\nA proper fix would be to split those states and track whether a cap\nupdate is actually in flight or has been observed by the MDS.\nHowever, simply moving the `cap->mds_wanted assignment` later would\nnot be sufficient: queueing the message in the messenger does not\nguarantee that the MDS processed that specific wanted set, and\nreconnect or message loss can still invalidate that assumption.\nFixing that properly would require a larger rework of the cap state\nmachine.\n\nTo allow simpler backports to stable kernels, this patch implements a\nsimpler workaround:\n\n- stop waiting forever in __ceph_get_caps(); after a bounded wait,\n fall back to the renew path\n\n- make ceph_renew_caps() issue a synchronous `OPEN` request whenever\n the inode still does not actually hold the wanted caps, instead of\n only calling ceph_check_caps()\n\nThe extra issued-vs-wanted check in ceph_renew_caps() is necessary\nbecause the previous test only checked whether the inode still had any\nreal caps at all. That is not enough after revocation: the client can\nstill hold something like `pLs` and yet be missing `FILE_RD`\ncompletely. In that case, falling back to ceph_check_caps() is not\nsufficient, because it still trusts `cap->mds_wanted` and may resend\nnothing. By requiring `(issued & wanted) == wanted` before taking the\nasynchronous path, the code only uses ceph_check_caps() when the\n`wanted caps` are already actually issued. Otherwise, it sends the\nsynchronous `OPEN` renew.\n\nThis preserves the existing asynchronous fast path when the wanted\ncaps are already issued, avoids changing cap-state semantics, and\nfixes the hang by guaranteeing that a stalled waiter eventually\nretries through a path that does not rely on the stale `mds_wanted`\nstate.\n\n[ idryomov: move CEPH_GET_CAPS_WAIT_TIMEOUT from libceph.h to\n

resolved:\n\nrbd: Reset positive result codes to zero in object map update path\n\nIn a reply message to an RBD request, a positive result code indicates\na data payload, which is not allowed for writes. While\nrbd_osd_req_callback() already resets a positive result code for writes\nto zero, rbd_object_map_callback() does not. This allows a corrupted\nreply to an object map update to trigger the rbd_assert(*result < 0) in\n__rbd_obj_handle_request(). This happens, because\nrbd_object_map_callback() calls rbd_obj_handle_request() ->\n__rbd_obj_handle_request() and passes this positive result code. From\n__rbd_obj_handle_request(), rbd_obj_advance_write() is called, which\nleaves the positive result code unchanged and returns true. Therefore,\nthe if(done && *result) branch is executed in __rbd_obj_handle_request()\nand the assertion triggers.\n\nThis patch fixes the issue by adjusting the logic in the\nrbd_object_map_callback() path. A positive result code for an object map\nupdate is now reset to zero (similar to rbd_osd_req_callback()), and the\nmessage is subsequently handled the same way as if the result code was\nzero from the beginning. Additionally, a WARN_ON_ONCE() is added for\nthis case.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

across write and release\nhandlers to parse user input.\n\nThe affected handler paths and their specific functions are:\n - Open paths: ftrace_regex_open(), ftrace_graph_open()\n - Write paths: ftrace_regex_write(), ftrace_graph_write()\n - Release paths: ftrace_regex_release(), ftrace_graph_release()\n\nIf userspace opens a trace file descriptor and shares it across multiple\nthreads, concurrent write calls will race on the parser's internal state,\nspecifically the 'idx', 'cont', and 'buffer' fields, leading to corrupted\ninput or undefined behavior.\n\nFix this by adding a global

If any of those later\nsteps fails, probe returns through the exit label after freeing only the\ncontrol handler.\n\nA failed probe does not call si476x_radio_remove(), so the\nv4l2_device_unregister() there is not reached.

resolved:\n\ndrm/dp/mst: fix buffer overflows in sideband chunk accumulation\n\ndrm_dp_sideband_append_payload() has three related bugs when processing\ndevice-provided sideband reply data:\n\n1. Zero-length curchunk_len underflow: msg_len is a 6-bit field taken\n directly from the DP sideband header. If a device sends msg_len=0,\n curchunk_len is set to zero. The condition (curchunk_idx >= curchunk_len)\n is immediately true, and curchunk_len-1 wraps to 255 (u8 underflow).\n drm_dp_msg_data_crc4() reads 255 bytes from chunk[48], then memcpy()\n writes 255 bytes into msg[], both far out of bounds.\n\n2. chunk[48] overflow: curchunk_len can reach 63 (6-bit field). chunk[] is\n only 48 bytes. Multi-iteration payload assembly appends 16-byte blocks\n until curchunk_idx reaches curchunk_len, writing up to 15 bytes past\n the end of chunk[] into msg[].\n\n3. msg[256] overflow: each chunk contributes (curchunk_len-1) bytes to\n msg[]. No check ensures curlen + (curchunk_len-1) stays within msg[256],\n so the memcpy can spill into adjacent struct fields.\n\nAll three are reachable from any DP MST device that can forge sideband\nreply messages on a physical connection.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\ncan: bcm: track a single source interface for ANYDEV timeout/throttle ops\n\nAn ANYDEV rx op (ifindex == 0) with an active RX timeout and/or\nthrottle timer has no defined semantics when matching frames arrive\nfrom several interfaces: bcm_rx_handler() can run concurrently for\nthe same op on different CPUs, racing hrtimer_cancel()/\nbcm_rx_starttimer() against bcm_rx_timeout_handler() and causing\nspurious RX_TIMEOUT notifications and last_frames corruption. The\nsame concurrency lets throttled multiplex frames from different\ninterfaces clobber the single rx_ifindex/rx_stamp fields shared by\nthe op.\n\nAdd op->if_detected to track the first interface that delivers a\nmatching frame while a timeout/throttle timer is configured, and\nreject frames from any other interface for that op. The claim is\ndecided in bcm_rx_handler() before hrtimer_cancel() touches\nop->timer, so a rejected frame can never disturb the claimed\ninterface's watchdog. RTR-mode ops are excluded via RX_RTR_FRAME,\nindependent of kt_ival1/kt_ival2, since those may briefly hold a\nstale value from an earlier non-RTR configuration.\n\nThe claim is released in bcm_notify() on NETDEV_UNREGISTER and in\nbcm_rx_setup() when SETTIMER reconfigures the timer values.\n\nA (re-)claim is only possible on CAN devices in NETREG_REGISTERED\ndev->reg_state to cover the release in bcm_notify() where reg_state\nbecomes NETREG_UNREGISTERING until synchronize_net().", "title": "Vulnerability description" } ], "product_status": { "fixed": [

Pin\nthe superblock with an active reference instead as\nfilesystems_freeze_callback() does. The active reference keeps the\nsuperblock from being shut down and so ->s_bdev stays valid without\nholding s_umount. The block-layer-held freeze is dropped by\nfs_bdev_thaw() with FREEZE_MAY_NEST | FREEZE_HOLDER_USERSPACE exactly as\na regular unfreeze would and thaw_super_locked() handles\nfilesystem-level freezes as before.\n\nThe emergency thaw path has deadlocked like this in one form or\nanother for a long long time but the current exclusively-held\nshape dates back to commit [1] where thaw_bdev() already ended in\nthaw_super() with s_umount held by do_thaw_all_callback().", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\nmips: sched: Fix CPUMASK_OFFSTACK memory corruption\n\nThis patch addresses a critical memory management flaw. When\nCONFIG_CPUMASK_OFFSTACK is enabled, cpumask_var_t is a pointer.\nConsequently, sizeof(new_mask) evaluates to the pointer size, causing\ncopy_from_user() to clobber the mask pointer. Furthermore, the old\nlogic performed copy_from_user() before allocating the mask.\n\nFix this by allocating new_mask first. To handle variable-sized user\nmasks correctly, use cpumask_size() to truncate overly large user masks\nor pad undersized masks with zeros before copying the data directly into\nthe allocated

rmi_f54_get_report_size():\n\n\treport_size = rmi_f54_get_report_size(f54);\n\t...\n\tfor (i = 0; i < report_size; i += F54_REPORT_DATA_SIZE) {\n\t\tint size = min(F54_REPORT_DATA_SIZE, report_size -

f54->num_rx_electrodes, sizeof(u16))),\nbut rmi_f54_get_report_size() computes the size from\ndrv_data->num_*_electrodes when those are set, i.e. from the F55\nfunction's electrode counts. Both counts come straight from device\nqueries (F54 and F55 each report up to 255 electrodes) and nothing\nconstrains the F55 counts to the F54 ones.\n\nA malicious or malfunctioning RMI4 device that reports larger F55\nelectrode counts than its F54 counts makes report_size exceed the\nallocation, so the read loop writes past report_data (and the V4L2\ndequeue memcpy() then reads past it). On conforming hardware the F55\nconfigured electrodes are a subset of the F54 physical electrodes, so\nreport_size never exceeds the buffer and well-behaved devices are\nunaffected.\n\nRecord the allocation size and reject a report that does not fit,\nmirroring the existing zero-size check.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nexec: fix unsigned loop counter wrap in transfer_args_to_stack()\n\nThe stop value is derived from bprm->p >> PAGE_SHIFT. The index variable\nis an unsigned long. If bprm->p drops below PAGE_SIZE and stop becomes\nzero the loop condition index >= stop is always true.\n\nAfter the index == 0 iteration the decrement wraps to ULONG_MAX and\nbprm->page[ULONG_MAX] reads sizeof(void *) bytes in front of the array.\nThe pointer has wrapped to -1. That garbage pointer is then passed to\nkmap_local_page() and PAGE_SIZE bytes are copied from wherever that\nlands into the stack of the process being created. And the loop doesn't\nterminate either...\n\nGetting there only requires bprm->p < PAGE_SIZE. On !MMU\nbprm_set_stack_limit() and bprm_hit_stack_limit() are empty. So the only\nconstraint on how far bprm->p is pushed down is valid_arg_len(), i.e.\nthat each individual string still fits in what is left.\n\nbprm->p starts at PAGE_SIZE * MAX_ARG_PAGES - sizeof(void *) so a\nsingle argument or environment string of a little over 31 pages leaves\nit in the first page:\n\n Oops - load access fault [#1]\n CPU: 0 UID: 0 PID: 1 Comm: victim Not tainted 7.2.0-rc4 #1\n epc : __memcpy+0xd4/0xf8\n ra : transfer_args_to_stack+0xaa/0xae\n s4 : ffffffffffffffff s2 : 0000000000000000\n a1 : ffffffdc98000000 a2 : 0000000000001000\n status: 0000000a00001880 badaddr: ffffffdc98000000 cause: 0000000000000005\n [<801a5324>] __memcpy+0xd4/0xf8\n [<800d5f6a>] load_flat_binary+0x43a/0x65e\n [<800a2de4>] bprm_execve+0x1d4/0x316\n [<800a351a>] do_execveat_common+0x12e/0x138\n [<800a3d44>] __riscv_sys_execve+0x38/0x4e\n Kernel panic - not syncing: Fatal exception in interrupt\n\nThis is an arcane bug but we should still fix it.\n\nCount down from MAX_ARG_PAGES so the loop ends when index reaches stop,\nstop == 0 included.

On a non-linear skb whose transport header sits in a page\nfragment, pskb_may_pull() can call __pskb_pull_tail() / pskb_expand_head()\nand free the old skb head, leaving ip6h dangling; the following\nget_csum_diff(ip6h, p) then reads freed memory. ila_update_ipv6_locator()\nuses ip6h (and the iaddr derived from it) again after the csum-adjust\ncall and additionally writes the new locator through that pointer.\n\nImpact: a remote IPv6 packet routed through a configured ILA\ncsum-adjust-transport route or receive-side mapping triggers a\nslab-use-after-free in ila_update_ipv6_locator() (KASAN). The route or\nmapping requires CAP_NET_ADMIN to configure, but trigger packets are\nunauthenticated once it exists.\n\nReload ip6h after each pskb_may_pull() in ila_csum_adjust_transport()\nbefore the csum-diff read. In ila_update_ipv6_locator() only the\nILA_CSUM_ADJUST_TRANSPORT case pulls the skb, so reload ip6h and iaddr in\nthat case alone before the destination-address write; the neutral-map\nmodes never

decrement set->ref.\nip_set_swap() holds that same lock while swapping both the ip_set_list\nslots and the two sets' ref counters, so it can interleave between the\ndereference and the lock acquisition, leaving the caller to decrement a\nset whose reference already moved to the other index and hit\nBUG_ON(set->ref == 0). list_set_gc() reaches this from timer softirq,\nwhich the nfnl mutex does not serialize against swap: an expiring\nlist:set member calls list_set_del() -> ip_set_put_byindex() while\nIPSET_CMD_SWAP runs on the referenced sets.\n\nResolve the index and decrement under ip_set_ref_lock, as ip_set_swap()\nalready does, keeping the refcount tied to the index rather than to a\nstale set pointer.\n\n kernel BUG at net/netfilter/ipset/ip_set_core.c:685!\n Oops:

resolved:\n\nusb: gadget: udc: bdc: free IRQ and drain func_wake_notify before teardown\n\nThe Broadcom BDC UDC driver registers its IRQ handler with\ndevm_request_irq() in bdc_udc_init(), so the IRQ is released by devm\nonly after bdc_remove() returns. devm releases resources in reverse\nLIFO order, but bdc_remove() runs bdc_udc_exit() and bdc_hw_exit() ->\nbdc_mem_free() manually before returning: bdc_udc_exit() tears down\nindividual endpoint objects via bdc_free_ep(), while bdc_hw_exit() ->\nbdc_mem_free() frees and NULLs the DMA-coherent status-report ring\n(bdc->srr.sr_bds) and kfree()s bdc->bdc_ep_array. Both happen while\nthe IRQ handler (bdc_udc_interrupt, requested with IRQF_SHARED)\nremains deliverable in the window up to the post-remove devm\nfree_irq().\n\nOn receipt of a shared interrupt in that window, bdc_udc_interrupt()\ndereferences bdc->srr.sr_bds[bdc->srr.dqp_index] (NULL or freed DMA)\nand dispatches sr_handler callbacks that index into bdc_ep_array,\ncausing a NULL-deref or use-after-free.\n\nThe same window affects the delayed_work bdc->func_wake_notify, which is\narmed from the IRQ handler via bdc_sr_uspc() -> handle_link_state_change()\n-> schedule_delayed_work() and may self-rearm from its own callback\nbdc_func_wake_timer(). No cancel exists anywhere in the driver, so a\nqueued work item that fires after bdc_remove() returns and the bdc\nstructure is devm-freed dereferences freed memory.\n\nReplace devm_request_irq() with request_irq() and add an explicit\nfree_irq(bdc->irq, bdc) in bdc_remove(). Clear BDC_GIE before\nfree_irq() to stop the device from asserting interrupts, then\nfree_irq() drains any in-flight handler, then cancel_delayed_work_sync()\ndrains the func_wake_notify delayed work. This ordering ensures the\nIRQ handler and delayed work cannot interfere with the subsequent\nendpoint and DMA teardown in bdc_udc_exit() and bdc_hw_exit(). Wire the\nmatching free_irq() into the bdc_udc_init() error path so the IRQ is\nreleased on probe failure, and route the bdc_init_ep() failure through\nerr0 instead of returning directly.\n\nThis

resolved:\n\nmm/page_reporting: use system_freezable_wq to fix UAF during suspend\n\nDuring PM freeze (e.g. S3 suspend or S4 hibernation), device drivers like\nvirtio_balloon reset their underlying virtio devices and delete their\nvirtqueues via vdev->config->del_vqs().\n\nHowever, page reporting work (page_reporting_process) was scheduled on the\nglobal system_wq. Because system_wq lacks the WQ_FREEZABLE flag, the PM\nfreezer skips it, leaving page_reporting_process active during suspend.\n\nIf pages are freed into the buddy allocator while suspending (for example,\nwhen core MM invokes the balloon shrinker during S4 hibernation image\nsaving), page reporting triggers virtballoon_free_page_report() on deleted\nvirtqueues, resulting in a Use-After-Free / General Protection Fault:\n\n [ 196.795226] general protection fault, probably for non-canonical address 0xaa1436fe70dae6df: 0000 [#1] SMP NOPTI\n [ 196.825967] Workqueue: events page_reporting_process\n [ 196.831038] RIP: 0010:virtqueue_add_split+0x233/0x4c0 [virtio_ring]\n [ 196.927073] virtballoon_free_page_report+0x3a/0xe0 [virtio_balloon]\n [ 196.946943] page_reporting_process+0x370/0x4f0\n\nFix this by switching page reporting work to system_freezable_wq. This\nensures that the PM freezer pauses page_reporting_process before device\ndrivers destroy their reporting virtqueues. Because the reporting worker\nis frozen, memory reclamation/freeing (e.g. via shrinker execution) can\nsafely return pages to MM during freeze without triggering unfrozen\nreporting work on deleted virtqueues.\n\nThis aligns with the driver's existing design. The comment in\nvirtballoon_freeze() states:\n /*\n * The workqueue is already frozen by the PM core before this\n * function is called.\n */\n\nTesting:\nI have verified these fixes using Google’s virtualization infrastructure\nby running continuous suspend/resume iterations (40+ cycles) while\nchurning memory using stress-ng (`stress-ng --vm 4 --vm-bytes 60%\n--timeout 1`) to constantly create free pages for the buddy allocator. We\nalso set the `page_reporting_order` parameter to 0 to make the page\nreporting worker highly sensitive, forcing it to pick up any 4K free\npages.

entry. In the\nVM-backed RMB path, splice_to_pipe() may drop unqueued entries through\nsmc_rx_spd_release(), while queued entries are released later via the\npipe buffer callback.\n\nThe old post-splice accounting also derives the number of queued VM pages\nfrom an offset mutated while building the descriptor, and a multi-page\nsplice pairs one sock_hold() with multiple sock_put() calls.\n\nTake the page and socket references for every candidate entry before\nsplice_to_pipe(), and drop the matching private state, page reference,\nand socket reference from smc_rx_spd_release() for entries that never\nget queued.

The additional\npinctrl_gpio_direction_input/output() calls do not add a Tegra pinctrl\noperation, because the Tegra pinmux ops provide GPIO request/free\nhandling but no gpio_set_direction hook.\n\nThe extra call still enters the pinctrl core and takes pctldev->mutex.\nShared GPIO users can call the direction path while holding their\nper-line spinlock, so this otherwise redundant pinctrl direction call can\nsleep in an atomic context.\n\nThis was found by our static analysis tool and then confirmed by manual\nreview of tegra_gpio_probe(), the Tegra GPIO direction callbacks and the\nTegra pinctrl ops. The reviewed path has a default non-sleeping\nstruct gpio_chip while the direction callback still enters the pinctrl\nmutex path.\n\nA directed runtime validation kept the same non-sleeping chip

resolved:\n\nlibceph: fix two unsafe bare decodes in decode_lockers()\n\ndecode_lockers() in cls_lock_client.c contains two bare decode operations\nthat allow a malicious or compromised OSD to trigger slab-out-of-bounds\nreads:\n\n1. ceph_decode_32(p) at the num_lockers field has no preceding bounds\n check. ceph_start_decoding() accepts struct_len=0 as valid -- the\n internal ceph_decode_need(p, end, 0, bad) always passes -- so when an\n OSD sends struct_len=0, ceph_start_decoding() returns success with\n p == end. The immediately following bare ceph_decode_32(p) then reads\n 4 bytes past the validated buffer boundary. The garbage value is\n passed directly to kzalloc_objs() as the locker count.\n\n The sibling function decode_watchers() in osd_client.c already uses\n ceph_decode_32_safe() after its own ceph_start_decoding() call.\n decode_lockers() was the only site using the bare variant.\n\n2. ceph_decode_8(p) after the decode_locker() loop has no preceding\n bounds check. If an OSD crafts num_lockers such that the loop\n advances p exactly to end, the subsequent bare ceph_decode_8(p) reads\n one byte past the validated buffer boundary. The result is passed\n directly into *type, which is used as a lock type discriminator by\n callers, giving an OSD-controlled one-byte OOB read with direct\n influence over the lock type field.\n\nFix both by replacing bare operations with their safe variants:\n ceph_decode_32(p) -> ceph_decode_32_safe(p, end, *num_lockers,\n err_inval)\n ceph_decode_8(p) -> ceph_decode_8_safe(p, end, *type,\n err_free_lockers)\n\nThe goto targets differ intentionally:\n err_inval: is a new label returning -EINVAL directly. It is used for\n the pre-allocation failure path where *lockers is not yet allocated\n and must not be passed to ceph_free_lockers().\n\n err_free_lockers: is the existing label. It is used for the\n post-allocation failure path where *lockers is allocated and must\n be freed.\n\nret is set to -EINVAL before ceph_decode_8_safe() so that\nerr_free_lockers returns the correct error code on bounds violation.\nWithout this, err_free_lockers would return a stale ret value (0 from\nthe successful decode_locker() loop), silently swallowing the error.\n\n-EINVAL is correct for both failure paths. The data received from the\nOSD is structurally malformed. -ENOMEM would misrepresent the failure\nclass to callers and to stable@ backporters triaging error paths.\n\nAttacker model: a malicious or compromised OSD in a multi-tenant Ceph\ndeployment can trigger this against any kernel client that issues the\nlock.get_info class method (e.g. during RBD exclusive lock acquisition).\n\n[ idryomov:

resolved:\n\nbinfmt_misc: set have_execfd only once the interpreter is opened\n\nload_misc_binary() raises bprm->have_execfd as soon as it sees the 'O'\n(or 'C') flag. This happens well before it opens the interpreter. If\nthat open fails the flag stays set on the bprm. binfmt_misc is at the\nhead of the format list so an interpreter open failure that returns\n-ENOEXEC lets the search fall through to a later format. This means it\nruns the matched binary directly having never staged an interpreter. So\nbprm->executable is NULL while have_execfd falsely claims a descriptor\nis present.\n\nConsequently, begin_new_exec() dereferences the missing executable:\n\n would_dump(bprm, bprm->executable);\n\nand NULL derefs. Had it not, the hand-off later in the same function\nwould have failed anyway. FD_ADD(0, bprm->executable) rejects a NULL\nfile with -ENOMEM. Both sites are past the point of no return so the\nexec cannot be unwound either way.\n\nThis can be reached by unprivileged users as binfmt_misc can be mounted\nin user namespaces. So a user can register an 'O' entry whose\ninterpreter lives on a FUSE mount, have the FUSE server fail the open\nwith -ENOEXEC and execute a native ELF file that matches the entry.\n\nhave_execfd only means anything alongside the executable it describes\nwhich is not set until the interpreter has been opened and staged.\nSo lets raise it there, next to execfd_creds, which is already set at\nthat point. An open failure now leaves it clear, so the fallback format\nderives credentials from the binary and emits no AT_EXECFD, as it would\nfor any native exec. The argv rewrite load_misc_binary() performs before\nthe open is still not undone. This means the binary sees the interpreter\npath in argv[0] and its own path in argv[1] but that predates this\nchange and only became observable once the exec stopped faulting.", "title":

These\ncached values are then used by the messenger connect code when\nsending the authorizer.\n\nceph_x_update_authorizer() can rebuild the authorizer when a newer\nservice ticket is available. If the rebuilt authorizer no longer\nfits in the existing buffer, ceph_x_build_authorizer() drops its\nreference to au->buf and allocates a new one. If this is the final\nreference, ceph_buffer_put() frees the old ceph_buffer and its\nvec.iov_base, but auth->authorizer_buf still points at that freed\nmemory.\n\nA subsequent msgr1 reconnect can therefore queue the stale pointer\nand trigger a KASAN slab-use-after-free in _copy_from_iter() while\ntcp_sendmsg() copies the authorizer.\n\nRefresh auth->authorizer_buf and auth->authorizer_buf_len

This causes too many bytes to be\nskipped for uptodate blocks, which results in returning the incorrect\nposition and length to read in.

Most\nqueue-dump callsites already serialize that walk under the socket lock or\nsk->sk_lock.slock, but tipc_poll() calls trace_tipc_sk_poll(...,\nTIPC_DUMP_ALL, ...) without holding either lock.\n\nThat lets the poll trace path reach tipc_list_dump() and backlog head/tail\ndumping while another context dequeues and frees an skb, leaving the trace\nhelper dereferencing a stale queue entry.\n\nStop the unlocked poll trace site from requesting queue dumps.

resolved:\n\nmtd: spi-nor: swp: Improve locking user experience\n\nIn the case of the first block being locked (or the few first blocks),\nif the user want to fully unlock the device it has two possibilities:\n- either it asks to unlock the entire device, and this works;\n- or it asks to unlock just the block(s) that are currently locked,\n which fails.\n\nIt fails because the conditions \"can_be_top\" and \"can_be_bottom\" are\ntrue. Indeed, in this case, we unlock everything, so the TB bit does not\nmatter. However in the current implementation, use_top would be true (as\nthis is the favourite option) and lock_len, which in practice should be\nreduced down to 0, is set to \"nor->params->size - (ofs + len)\" which is\na positive number. This is wrong.\n\nAn easy way is to simply add an extra condition. In the unlock() path,\nif we can achieve the same result from both sides, it means we unlock\neverything and lock_len must simply be 0.

ref_pic_list0/ref_pic_list1 entries from the\nstateless slice control and later uses their indices to look up\ndecode->dpb[] in _cedrus_write_ref_list().\n\nRejecting such controls in cedrus_try_ctrl() would break existing\nuserspace, since stateless H.264 reference lists may legitimately carry\nout-of-range indices for missing references. Instead, guard the actual\nDPB lookup in Cedrus and skip entries whose indices do not fit the fixed\nV4L2_H264_NUM_DPB_ENTRIES array.\n\nThis keeps the fix local to the driver use site and avoids out-of-bounds\nreads from malformed or unsupported reference list entries.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nwifi: mwifiex: use the subframe length when parsing A-MSDU TDLS frames\n\nmwifiex_11n_dispatch_amsdu_pkt() splits an A-MSDU with\nieee80211_amsdu_to_8023s() and walks the resulting subframes. For each\nsubframe it passes the subframe data pointer to\nmwifiex_process_tdls_action_frame(), but pairs it with skb->len, the\nlength of the A-MSDU parent, instead of rx_skb->len:\n\n\trx_skb = __skb_dequeue(&list);\n\trx_hdr = (struct rx_packet_hdr *)rx_skb->data;\n\tif (ISSUPP_TDLS_ENABLED(priv->adapter->fw_cap_info) &&\n\t ntohs(rx_hdr->eth803_hdr.h_proto) == ETH_P_TDLS) {\n\t\tmwifiex_process_tdls_action_frame(priv, (u8 *)rx_hdr,\n\t\t\t\t\t\t skb->len);\n\t}\n\nThe parent is not a valid description of that buffer, and may not be\nvalid memory at all. ieee80211_amsdu_to_8023s() ends with\n\n\tif (!reuse_skb)\n\t\tdev_kfree_skb(skb);\n\nand it only sets reuse_skb when the parent is linear, is not a\nhead_frag, and is being consumed as the *last* subframe. So when the\nparent does not qualify for reuse it has already been freed, and the\nread of skb->len is a use-after-free. When it is reused, skb->len is\nthe length of the last subframe, applied to every earlier subframe,\nwhich over-states the buffer whenever an earlier subframe is shorter.\n\nThe callee cannot absorb a wrong length, because it derives its own\nceiling from the value it is given. Each frame type computes\n\n\ties_len = len - sizeof(struct ethhdr) - TDLS_*_FIX_LEN;\n\nand the element walk is then bounded entirely against that ceiling,\n\n\tfor (end = pos + ies_len; pos + 1 < end; pos += 2 + pos[1]) {\n\t\tu8 ie_len = pos[1];\n\n\t\tif (pos + 2 + ie_len > end)\n\t\t\tbreak;\n\nso a too-large len moves end past the end of the subframe and the walk\nreads and copies beyond it. The A-MSDU layout is chosen by the sender,\nwhich makes the difference between the last subframe and a shorter\nearlier one remotely selectable. Reaching this requires TDLS support in\nfirmware and the TDLS ethertype on the subframe.\n\nThe other caller, mwifiex_process_rx_packet(), is correct: it passes a\npointer and a length that describe the same region of the RX buffer.\n\nPass rx_skb->len, the length of the subframe actually being parsed.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\ntracing: Fix resource leak on mmiotrace trace_pipe close\n\nThe mmiotrace tracer was added May 12th 2008. At that time, resources\ncreated in pipe_open() could not be freed because there was not\npipe_close function pointer of the tracer. The pipe_close function pointer\nwas added in December 7th, 2009, but the mmiotrace tracer was not updated.\n\nmmio_pipe_open() allocates a header_iter and takes a pci_dev reference\nwhen trace_pipe is opened. mmio_close() frees them, but it was only\nwired to the tracer's .close callback.\n\ntracing_release_pipe() invokes .pipe_close, not .close, when the\ntrace_pipe file is released. As a result, closing trace_pipe with the\nmmiotrace tracer active leaked the header_iter allocation and left a\nstale pci_dev reference.\n\nSet .pipe_close to mmio_close, matching how function_graph wires both\ncallbacks to the same handler.\n\nNote, if the trace_pipe is read to completion, it will clean up the\nresources, but if one were to run:\n\n # head -n 1 /sys/kernel/tracing/trace_pipe\n VERSION 20070824\n\nOver and over again, it would trigger a massive leak.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nairspy_start_streaming() returned -ENODEV early when the USB device had\nbeen disconnected (s->udev == NULL) without returning any buffers that\nbuf_queue() had already accepted. Take v4l2_lock first and jump to the\nexisting err_clear_bit label, which already drains s->queued_bufs via\nvb2_buffer_done(..., VB2_BUF_STATE_QUEUED) before unlocking.\n\nThis mirrors the uvcvideo

resolved:\n\nstaging: rtl8723bs: fix OOB read in rtw_get_wpa_ie()\n\nrtw_get_wpa_ie() reads bytes at fixed offsets into a vendor-specific\ninformation element without checking that the element is long enough,\ncausing an out-of-bounds read for a short trailing IE.\n\nThe function locates a vendor-specific IE (EID 221) with rtw_get_ie()\nand then compares a 4-byte OUI+type at pbuf + 2 and reads a 2-byte\nversion word at pbuf + 6. Those accesses require the IE body to be at\nleast 6 bytes, but rtw_get_ie() only guarantees that the element fits\nwithin the buffer; it does not enforce a minimum body length. A\nvendor-specific IE whose length byte is 0 to 5, placed at the end of\nthe buffer, therefore makes these reads run past the end of the IE and\npast the end of the buffer itself.\n\nThe buffer holds information elements taken from received management\nframes and from the IE blob passed to rtw_cfg80211_set_wpa_ie(), which\nis kmemdup'd to its exact length, so the read can run off the end of\nthe allocation.\n\nThe sibling helpers rtw_get_sec_ie(), rtw_get_wapi_ie() and\nrtw_get_wps_ie() in this file already reject too-short vendor-specific\nIEs before their OUI memcmp(); rtw_get_wpa_ie() was never brought in\nline with them, and needs a minimum of 6 rather than 4 bytes because\nof the version word.

If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nsun4i_csi_start_streaming() returned -EINVAL when no matching CSI\nformat could be found, before any setup (scratch buffer allocation,\npipeline start) had been performed. The remaining error paths already\nconverge on the err_clear_dma_queue label, which calls\nreturn_all_buffers(..., VB2_BUF_STATE_QUEUED) under csi->qlock. Jump\nto that label directly: the intermediate err_disable_device /\nerr_disable_pipeline / err_free_scratch_buffer labels are skipped,\nwhich is correct because nothing they would undo has happened

resolved:\n\nfutex: Prevent robust futex exit race some more\n\nA robust futex unlock stores 0 over the whole futex value - wiping\nFUTEX_WAITERS - and wakes a single waiter. That wakeup is a one-shot\nnotification: the protocol relies on its recipient to either acquire the\nfutex (and eventually unlock while aware of the remaining contention) or\nre-arm FUTEX_WAITERS before sleeping again. If the woken waiter is killed\nbefore it can do either, the kernel must jump in and wake the next task\ndown the line.\n\nThis is a known complication of the futex protocol with a previous\npartial fix in commit ca16d5bee598 (\"futex: Prevent robust futex exit\nrace\"). Unfortunately, that fix is insufficient.\n\nIf a third task re-acquired the futex through the uncontended fast\npath in the meantime, the notification is lost: robust exit processing\nsees that it is owned by another task and does nothing, while the new\nowner sees no FUTEX_WAITERS when it unlocks and wakes nobody.\nThe remaining waiters sleep forever behind a free futex:\n\n A owns the futex, B and C sleep in FUTEX_WAIT\n uval == A | FUTEX_WAITERS\n A robust unlock: store 0, FUTEX_WAKE(1) wakes B\n uval == 0\n D fast path acquire: cmpxchg(0 -> D)\n uval == D, no FUTEX_WAITERS\n B killed before acting on the wakeup\n B exit walk, pending op: owner D != B -> no action\n D unlock: no FUTEX_WAITERS -> no wake\n C sleeps forever\n\nThis is clearly a shortcoming in the implementation, which fails to keep\nthe FUTEX_WAITERS bit consistent.\n\nWork around this by augmenting the robust list exit processing to also\nperform the extra wakeup if the futex word is owned by another thread but\nFUTEX_WAITERS is not set.\n\nThis does not fix the problem of a non-contended take over/release and free\nsequence, which has been discussed for years and has been addressed by\ncommit 3ca9595d9fb6 (\"futex: Add support for unlocking robust futexes\") and\nsubsequent changes, but failed to take the problem described above into\naccount.\n\nA more complete solution which is based on the in kernel unlock of\ncontended robust futexes has been discussed in the context of this change\nand should show up in mainline sooner than later.\n\n[ tglx: Amend change log slightly and fixup

callback. lbtf_free_adapter()\nruns on the teardown path right before ieee80211_free_hw() frees priv,\nboth in lbtf_remove_card() and in the probe error path. command_timer is\narmed by mod_timer() in lbtf_cmd() whenever a firmware command is sent.\ncommand_timer_fn() dereferences priv. If a command times out as the\ndevice is removed, command_timer_fn() runs concurrently with teardown and\ndereferences priv after it has been freed.\n\nThis is the same use-after-free that commit 03cc8f90d053 (\"wifi: libertas:\nfix use-after-free in lbs_free_adapter()\") fixed in the sibling libertas\ndriver. The libertas_tf variant has the identical pattern and was left\nunchanged.

pointer.\nCopying only selected fields is fragile because pointer provenance is\ntracked by several bpf_reg_state fields.\n\nUse the caller's temporary offset register to preserve the scalar

So, if it fails and we return right\naway, the skb ends up leaked.\n\nFix that by breaking instead and letting the common error handling\ncode at the bottom of the loop to free the skb properly.\n\nThis is a very unlikely scenario as it requires the packet to become\nunparseable by applying a set of actions on a previously parseable skb,\nbut should be fixed

maximum. When a user\nsets the MTU to a value exceeding U16_MAX (65535), it passes validation\nbut is silently truncated when assigned to u16 fields l->mtu and\nl->advertised_mtu in tipc_link_create(). Values like 65536 (0x10000)\ntruncate to 0, causing a division by zero in tipc_link_set_queue_limits()\nwhich computes TIPC_MAX_PUBL / (l->mtu / ITEM_SIZE). Other overflowing\nvalues (e.g. 65537-131071) produce small incorrect MTU values, resulting\nin link malfunction behaviors.\n\nCrash stack (triggered as unprivileged user via user namespace):\n\n tipc_link_set_queue_limits net/tipc/link.c:2531\n tipc_link_create net/tipc/link.c:520\n tipc_node_check_dest net/tipc/node.c:1279\n tipc_disc_rcv net/tipc/discover.c:252\n tipc_rcv

resolved:\n\ndrm/vc4: Zero the tile state data array before each BIN job\n\nThe binner BO is a single 16MB buffer split into 512KB slots that are\nhanded out to jobs at submission time and recycled as jobs complete,\nwithout ever being cleared. Each slot holds the job's Tile State Data\nArray (TSDA) at its start, followed by the tile allocation pool.\n\nWhile the tile allocation pool is only walked by the render thread\nthrough branches the binner generated during the current job, the\nTSDA is the PTB's own per-tile bookkeeping and is consumed by the\nhardware itself. Although the kernel sets the \"Auto-initialise Tile\nState Data Array\" flag in the tile binning mode configuration, the\nPTB demonstrably still acts on stale tile state left by the slot's\nprevious user: the binner ends up creating invalid command streams\nwith invalid primitive streams and branches, which can cause GPU hangs\nas observed in [1][2].\n\nZero the TSDA when the job's binning slot is configured. This clears\n48 bytes per tile (~24KB for a 1080p frame) in the submission path, and\nguarantees the PTB never sees another job's tile state.\n\nThe tile count is only checked for being non-zero today, so the 8-bit\nfields it comes from can describe a tile state array almost six times\nlarger than the slot it has to live in. Bound it before the slot is\nhanded out, since such size decides how much of the slot is left for\nthe tile alloc pool.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

up in an extension\nnon-inheritance list. It does so after testing elem->id, but without\nverifying that the element actually has a data octet. A zero-length\nextension element (WLAN_EID_EXTENSION with length 0) therefore makes it\nread one octet past the end of the element.\n\n_ieee802_11_parse_elems_full() runs this check for every element of a\nframe once a non-inheritance context exists -- e.g. while parsing a\nper-STA profile of a Multi-Link element in a (re)association response,\nor a non-transmitted BSS profile -- so a crafted frame from an AP can\ntrigger a one-octet slab-out-of-bounds read during element parsing:\n\n BUG: KASAN: slab-out-of-bounds in cfg80211_is_element_inherited\n Read of size 1 ... in

resolved:\n\nthunderbolt: Prevent XDomain delayed work use-after-free on disconnect\n\ntb_xdp_handle_request() runs on system_wq and queues\nxd->state_work via queue_delayed_work() in three request handlers:\nPROPERTIES_CHANGED_REQUEST, UUID_REQUEST (via start_handshake),\nand LINK_STATE_CHANGE_REQUEST. Similarly, update_xdomain() queues\nxd->properties_changed_work when local properties change.\n\nConcurrently, tb_xdomain_remove() calls stop_handshake() which does\ncancel_delayed_work_sync() on both delayed works. Later,\ntb_xdomain_unregister() calls device_unregister() which eventually\nfrees the xdomain. Since commit 559c1e1e0134 (\"thunderbolt: Run\ntb_xdp_handle_request() in system workqueue\") moved the request\nhandler off tb->wq, the handler and the remove path are no longer\nserialized. If queue_delayed_work() executes after\ncancel_delayed_work_sync() but before the xdomain is freed, the\ndelayed work fires on a freed object.\n\nAdd xd->removing that tb_xdomain_remove() sets under xd->lock\nbefore calling stop_handshake(). Each external queue site holds\nthe same lock and checks removing before calling\nqueue_delayed_work(). This provides the mutual exclusion needed:\neither the queue site acquires the lock first and queues work that\nthe subsequent cancel will see, or the remove path acquires the\nlock first and the queue site observes removing == true and skips\nthe queue.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\nnet: gro: fix double aggregation of flush-marked skbs\n\nCommit 0ab03f353d36 (\"net-gro: Fix GRO flush when receiving a GSO\npacket.\") added a flush check to skb_gro_receive(), but\nskb_gro_receive_list() lacks the same validation.\n\nAs a result, packets marked with NAPI_GRO_CB(skb)->flush may still be\nre-aggregated.\n\nThis allows already-GRO'd packets with existing frag_list to be\nre-aggregated into a new GRO session, corrupting the frag_list chain\nstructure. When skb_segment() attempts to unpack these malformed packets,\nit encounters invalid state and triggers a kernel panic.\n\nScenario (Tethering/Device forwarding):\n 1. Driver: Generated aggregated packet P1 via LRO with frag_list\n 2. Dev A: Receives aggregated fraglist packet and flush flag set\n 3. Dev A: Re-enters GRO, skb_gro_receive_list() is called\n 4. Missing flush check allows re-aggregation despite flush flag\n 5. Frag_list chain becomes corrupted (loops or dangling refs)\n 6. Dev B: TX path calls skb_segment(), crashes on corrupted frag_list\n\nRoot cause in skb_segment():\n The check at line ~4891:\n if (hsize <= 0 && i >= nfrags && skb_headlen(list_skb) &&\n (skb_headlen(list_skb) == len || sg)) {\n\n When frag_list is corrupted by double aggregation, when list_skb is\n a NULL pointer from skb->next, skb_headlen(list_skb) dereference\n NULL/corrupted pointers occurs.\n\nCall Trace:\n skb_headlen(NULL skb)\n skb_segment\n tcp_gso_segment\n tcp4_gso_segment\n inet_gso_segment\n skb_mac_gso_segment\n __skb_gso_segment\n skb_gso_segment\n

resolved:\n\nnet: openvswitch: fix potential UAF on meter attach failure\n\nWhile attaching a newly created meter attach_meter() function makes\nthe new meter visible to other CPUs but can still fail afterwards.\nOn failure, it detaches the meter back and returns an error.\n\nHowever, this is an unexpected behavior for the ovs_meter_cmd_set()\nthat uses a plain kfree(meter) on attach failure without waiting for\nRCU readers to stop using it, assuming it was never visible.\n\nThis is never a problem for ovs-vswitchd as it always creates meters\nbefore creating any flows that use them. But the UAF can be triggered\nwith a custom application using uAPI:\n\n BUG: KASAN: slab-use-after-free in ovs_meter_execute (net/openvswitch/meter.c:653)\n Read of size 8 at addr ffff88810d152650 by

flagged URB_FREE_BUFFER so that the final usb_free_urb() also\nfrees the transfer buffer.\n\nIf usb_submit_urb() fails, the error path frees the buffer explicitly with\nkfree(buf) and then calls usb_free_urb(urb). Because URB_FREE_BUFFER is set,\nusb_free_urb() -> urb_destroy() frees the same buffer a second time, a double\nfree of the transfer buffer.\n\n BUG: KASAN: double-free in usb_free_urb.part.0+0x91/0xb0\n Free of addr ffff8881069ccb80 by task trigger.sh/285\n\n Call Trace:\n kfree+0x113/0x3c0\n usb_free_urb.part.0+0x91/0xb0\n\nDrop the redundant kfree(buf); usb_free_urb() already releases the transfer\nbuffer.

A\nconnected HIDP peer can send an empty basic-mode SDU and make both paths\nuse an uninitialized byte from skb tailroom.\n\nKMSAN reports the use in hidp_session_run(), with the uninitialized value\noriginating in __alloc_skb() through vhci_write(). The control path\nproduces two reports and the interrupt path produces one.\n\nThe byte can also be controlled by a malformed lower-layer packet. If an\nHCI ACL packet contains an L2CAP PDU with a declared zero-length payload\nfollowed by an extra 0x15 byte, l2cap_recv_acldata() reduces skb->len to\nthe declared PDU length before dispatch. The current HIDP path nevertheless\nconsumes the extra byte as HIDP_TRANS_HID_CONTROL |\nHIDP_CTRL_VIRTUAL_CABLE_UNPLUG and terminates the HIDP session. With this\nchange, the same packet is discarded and a subsequent feature report\nrequest succeeds.\n\nPull the transaction header with skb_pull_data() and discard frames that\ndo not contain it.",

While the cancel waits for any running instance\nof i2c_gate_work to finish, it does not prevent the timer from being\nrescheduled by a concurrent thread.\n\nDuring probe, the r820t_attach() call attempts I2C transfers through\nthe mux adapter. These transfers go through i2c_mux_master_xfer(),\nwhich calls rtl2832_deselect() after the transfer completes,\nrescheduling i2c_gate_work via schedule_delayed_work(). If this\ntransfer is still in flight when rtl2832_remove() runs,\nrtl2832_deselect() can reschedule i2c_gate_work after it has been\ncancelled, causing a use-after-free when kfree(dev) is called.\n\nFix this by calling i2c_mux_del_adapters() before\ncancel_delayed_work_sync(). Once the mux adapter is unregistered, no\nnew I2C transfers can go through it, so rtl2832_deselect() can no\nlonger reschedule i2c_gate_work.

resolved:\n\nnet/sched: act_gact, act_police: range check the fallback control action\n\ntcf_action_check_ctrlact() range checks the primary control action:\n\n\tif (!opcode)\n\t\tret = action > TC_ACT_VALUE_MAX ? -EINVAL : 0;\n\nTC_ACT_VALUE_MAX is TC_ACT_TRAP, so kernel-internal verdicts above it\ncannot be set that way. But act_gact and act_police each carry a second,\nindependent control action supplied by user space that never reaches that\nhelper - TCA_GACT_PROB.paction and TCA_POLICE_RESULT. Both only reject\nTC_ACT_GOTO_CHAIN, so any other value is stored verbatim and returned\nverbatim from the action.\n\nIn particular user space can store TC_ACT_CONSUMED, which is\nTC_ACT_VALUE_MAX + 1 and is deliberately not part of the UAPI value\nrange. That verdict tells every caller the action took ownership of the\nskb, so nobody frees it: sch_handle_ingress(), sch_handle_egress() and\ntcf_qevent_handle() all deliberately skip the free for it. The result is\none leaked sk_buff plus its data buffer per packet traversing the filter,\nunbounded, for all traffic on the chain including kernel-generated\npackets.\n\nBoth are trivially deterministic. act_gact clamps tcfg_pval to >= 1, so\nwith pval = 1 gact_determ() returns the fallback for every packet.\nact_police has no mandatory rate, so rate = 0 leaves tcfp_mtu = ~0 and\ntcf_police_mtu_check() always passes.\n\nTC_ACT_CONSUMED was added by commit 720f22fed81b (\"net: sched: refactor\nreinsert action\"), after both goto-chain guards were written:\ncommit 9469f375ab09 (\"net/sched: act_gact: disallow 'goto chain' on\nfallback control action\") and\ncommit c08f5ed5d625 (\"net/sched: act_police: disallow 'goto chain' on\nfallback control action\"). Neither guard was widened when the new\nverdict appeared.\n\nFactor the existing range test out of tcf_action_check_ctrlact() as\ntcf_action_valid() and apply it to both fallbacks. The helper cannot call\ntcf_action_check_ctrlact() directly because that also allocates a\ngoto_chain, which is exactly what these two sites must not do.\n\nReproduced on v7.2-rc6: kmemleak reports one leaked 232-byte\nskbuff_head_cache object plus its 704-byte data buffer per packet. With\nthis patch both configurations are rejected with -EINVAL and kmemleak\nreports none.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

every gateway is\nencoded as an IPv4 RTA_GATEWAY attribute. IPv4 routes can also carry an\nIPv6 gateway, which fib_nexthop_info() dumps as RTA_VIA.\n\nAs a result, route notifications can allocate an skb that is too small.\nfib_dump_info() then fails with -EMSGSIZE and rtmsg_fib() hits the\nWARN_ON() that marks such failures as a fib_nlmsg_size() bug. With\npanic_on_warn set, this becomes a kernel panic.\n\nMirror the actual nexthop dump layout in fib_nlmsg_size(): account for\nIPv6 nexthop gateways dumped as RTA_VIA, for the no-header

resolved:\n\nserial: 8250_dma: Clear stale RX state on shutdown\n\nserial8250_release_dma() terminates RX DMA and releases the channel, but\nleaves rx_running set. If the port is closed while an RX transfer is\nactive, the stale state remains while rxchan is NULL until the channel is\nrequested again on the next open.\n\nThe DesignWare BUSY workaround added by commit a7b9ce39fbe4\n(\"serial: 8250_dw: Ensure BUSY is deasserted\") calls\nserial8250_rx_dma_flush() from the LCR write path during startup. This\nhappens before serial8250_request_dma() obtains a new RX channel. On\nreopen, the stale rx_running state therefore makes the flush path pass a\nNULL channel to dmaengine_pause(), causing a kernel Oops.\n\nClear rx_running after terminating RX DMA, matching the TX cleanup. Also\nmake the flush helper return if the DMA object or RX channel is not\navailable so startup and teardown paths cannot pass a NULL channel to the\nDMAengine API.", "title": "Vulnerability

resolved:\n\npacket: use consistent hard_header_len in non-ring send paths\n\npacket_snd() reads dev->hard_header_len multiple times while allocating\nand constructing an skb. Device reconfiguration can change this value\nconcurrently, for example through bonding device type changes.\n\nFor SOCK_RAW, packet_snd() can save a larger value in reserve and later\nallocate headroom using a smaller value. Moving skb->data back by reserve\nthen places it before skb->head, and the following copy from userspace can\nattempt an out-of-bounds write.\n\npacket_sendmsg_spkt() has the same issue because it calculates its\nreservation and header offset from separate reads before dropping the RCU\nread lock to allocate the skb.\n\nAdd LL_RESERVED_SPACE_EX() for callers that already saved a header length.\nRead hard_header_len once in packet_snd() and use it for allocation and\nconstruction. In packet_sendmsg_spkt(), preserve the allocation-time value\nthrough the device lookup retry.\n\nThe separate SOCK_DGRAM consistency problem between hard_header_len and\nheader_ops->create is not

available starting from skb->data.\n\nHowever, in vxlan_xmit(), skb->data points to the MAC header, so\nskb_network_offset(skb) is ETH_HLEN (14 bytes). Using pskb_may_pull(skb, 20)\nonly checks 20 bytes from skb->data (which is 14 bytes MAC header + 6 bytes of\nIP header), leaving the rest of the IP header potentially un-pulled in non-linear\nfrags. Subsequent dereferences of ip_hdr(skb)->daddr can read beyond the pulled\nlinear buffer length.\n\nFix this by using pskb_network_may_pull(), which adds skb_network_offset(skb) to\nthe length check to

resolved:\n\nfirewire: net: Fix fragmented datagram reassembly\n\nfwnet_frag_new() keeps a sorted list of received fragments for a partial\ndatagram. When a new fragment is adjacent to an existing fragment, the\ncode checks whether the new fragment also closes the gap to the next or\nprevious list entry.\n\nThose neighbor lookups currently assume that the current fragment always\nhas a real next or previous fragment. At a list edge, the next or\nprevious entry is the list head, not a struct fwnet_fragment_info.\n\nThe gap checks also compare against the old edge of the current fragment\ninstead of the edge after adding the new fragment. As a result, a\nfragment that bridges two existing ranges may leave two adjacent ranges\nunmerged, so fwnet_pd_is_complete() can miss a complete datagram.\n\nCheck for the list head before looking up the neighboring fragment, and\ncompare the neighbor against the new fragment's far edge when deciding\nwhether to merge all three ranges.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

protects list membership\nwhile the lookup is in progress, but it does not pin a socket's lifetime\nafter the lock is dropped.\n\nThe function currently drops x25_list_lock before calling lock_sock(s). A\nconcurrent close can run x25_release(), remove the same socket from\nx25_list, and drop the last socket reference in that window. The neighbour\nteardown path can then lock or inspect a freed struct sock/struct x25_sock.\n\nTake sock_hold(s) while x25_list_lock still proves that the list entry is\nlive, then drop the temporary reference after the socket has been locked,\nrechecked, and released. Recheck x25_sk(s)->neighbour after lock_sock(),\nbecause another path may have disconnected the socket before this path\nacquired the socket lock. Restart the list walk after each disconnect\nbecause the list lock was dropped and the previous iterator state may no\nlonger be valid.\n\nA QEMU/KASAN run against origin/master reproduced a

source/destination MAC\nbytes forward and make room for the SecTAG.\n\nOn the AF_PACKET SOCK_RAW + PACKET_QDISC_BYPASS transmit path the skb\nreaches the macsec ndo_start_xmit() with the MAC header unset, so\neth_hdr(skb) resolves to skb->head + (u16)~0 and the read is out of\nbounds: a 12-byte heap over-read that is also emitted on the wire as the\nframe's outer source/destination MAC. KASAN reports a slab-out-of-bounds\nread in macsec_start_xmit() on 6.0; on current mainline a CONFIG_DEBUG_NET\nbuild flags it as an unset mac header in skb_mac_header().\n\nOn the TX path the L2 header is at skb->data, so use skb_eth_hdr(), added\nby commit 96cc4b69581d (\"macvlan: do not assume mac_header is set in\nmacvlan_broadcast()\") for exactly this purpose.", "title": "Vulnerability

resolved:\n\nNTB: ntb_netdev: Preserve RX queue depth on allocation failure\n\nntb_netdev_rx_handler() hands the received skb to the network stack\nbefore allocating its replacement. If the allocation fails, nothing is\nreposted. Every failure therefore takes one buffer out of the RX queue\nwhile the interface remains up, and enough failures eventually stall\nreception.\n\nA retry path could refill the queue later, but ntb_netdev has none.\nAllocate the replacement first instead. If that fails, drop the packet\nand repost the same skb. This keeps the queue full and lets packet\ndelivery resume as soon as memory is available again.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nnetfilter: ebt_nflog: pin the NFLOG backend\n\nnf_log_unregister() runs after the per-net teardown so its final RCU\ngrace period also drains readers that obtained the logger from a per-net\nbinding. However, ebt_nflog passes an explicit ULOG log type to\nnf_log_packet() without holding a reference on the selected logger module,\nunlike the xt_NFLOG and nft_log frontends.\n\nAn ebtables nflog rule can therefore remain callable while nfnetlink_log\nis unloaded. The resulting interleaving is:\n\n CPU 0 CPU 1\n nfnetlink_log_fini()\n unregister_pernet_subsys()\n kfree(nfnl_log_pernet(net))\n ebt_nflog_tg()\n nf_log_packet()\n nfulnl_log_packet()\n instance_lookup_get_rcu()\n\nThe global ULOG logger is still registered at this point, so CPU 1\ndereferences the per-net state after CPU 0 has freed it.

the datagram fits within the\ndeclared block length. Additionally, when decoding multiple NTBs from a\nsingle socket buffer, subsequent block lengths are not checked against the\nactual remaining buffer data.\n\nWith these checks missing, a malicious USB host can specify datagram\noffsets and lengths that point beyond the block, or supply secondary NTB\nheaders declaring lengths larger than the buffer. skb_put_data() then\ncopies adjacent kernel memory from skb_shared_info into the network skb.\n\nFix this by verifying that sufficient buffer space remains for the NTB\nheader before parsing, handling zero-length block declarations, ensuring\nthat block lengths never exceed the remaining buffer space, and verifying\nthat each datagram payload stays strictly within the block boundary.", "title": "Vulnerability description" } ],

lists and waiting for a\ngrace period. Concurrent readers in `audit_filter()` and\n`audit_filter_rules()` still dereference `e->rule.exe`, while the fsnotify\nmark can be freed on an independent lifetime path.

resolved:\n\nALSA: pcm: wake linked drain waiters on unlink\n\nsnd_pcm_drain() on a linked stream parks an on-stack wait entry on the\ndrained peer's runtime->sleep, and after schedule_timeout() removes it\nonly if that peer is still found in the caller's group. If group\nmembership changes during the wait and the sleep ends by signal or\ntimeout (so autoremove_wake_function() does not run), finish_wait() is\nskipped and snd_pcm_drain() returns with the entry still queued on that\nstream's sleep list; a later wake_up() then walks a freed stack frame.\nThis is reachable by unlinking either the drained or the draining stream.\n\nUnlike the close path (snd_pcm_drop() -> snd_pcm_post_stop()),\nsnd_pcm_unlink() never wakes the sleep queues. Wake every group member\nunder the group lock before the membership change, so a linked drainer is\nreleased and drops its entry while the streams are still grouped.\n\nThe window was opened when snd_pcm_link_rwsem stopped being held across\nthe wait and the removal became conditional on group membership (see\nFixes). The later switch to finish_wait() kept that conditional removal,\nso the signal/timeout case remained.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

urb_packs;\n\tu->buffer_size = maxsize * u->packets;\n\n\tif (fmt->fmt_type == UAC_FORMAT_TYPE_II)\n\t\tu->packets++; /* for transfer delimiter */\n\tu->urb = usb_alloc_urb(u->packets, GFP_KERNEL);\n\nbuffer_size is computed from the pre-increment packet count and never\nrecomputed, so for a Type II endpoint the buffer is one packet short of\nthe packet count the URB is built with.\n\nprepare_inbound_urb() then lays out one iso frame per packet and never\nconsults buffer_size:\n\n\toffs = 0;\n\tfor (i = 0; i < urb_ctx->packets; i++) {\n\t\turb->iso_frame_desc[i].offset = offs;\n\t\turb->iso_frame_desc[i].length = ep->curpacksize;\n\t\toffs += ep->curpacksize;\n\t}\n\n\turb->transfer_buffer_length = offs;\n\turb->number_of_packets = urb_ctx->packets;\n\nThe last descriptor therefore points one packet past the end of the\ntransfer buffer, where the host controller writes device data on every\ninbound transfer. prepare_silent_urb() and prepare_playback_urb() bound\ntheir fill loops by ctx->buffer_size, so only capture is affected.\n\nfmt_type comes from the device's audio streaming descriptors, so any\ndevice advertising a Type II capture format hits this once userspace sets\nhw_params on the stream.\n\nKASAN on 7.2.0-rc5 (arm64) with a dummy_hcd/raw-gadget device, one report\nper inbound transfer:\n\n BUG: KASAN: slab-out-of-bounds in dummy_timer\n

resolved:\n\nfbdev: bitblit: bound-check glyph index in bit_cursor()\n\nbit_cursor() fetches the glyph under the cursor with\n\n\tc = scr_readw(vc_pos);\n\tsrc = vc_font.data + ((c & charmask) * w * height);\n\nwhere charmask is 0x1ff when vc_hi_font_mask is set. The screen buffer\nvalue comes directly from scr_readw() and may be larger than the current\nfont's glyph count.\n\nSyzkaller triggers this via vcs_write(). The Call Trace shows\nvcs_write() in vc_screen.c writing an arbitrary 16-bit value with\nwritev() to /dev/vcsa, which vcs_write_buf() in vc_screen.c stores via\nvcs_scr_writew() without checking charcount. The stored value is later\nread in bit_cursor() in bitblit.c.\n\nWhen the font is changed from a font with 512 glyphs to a font with\n256 glyphs, the screen buffer can retain characters with the high\nbit set from the previous mode, which could also produce the same\nout-of-bounds access.\n\n BUG: KASAN: global-out-of-bounds in soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70\n Read of size 16 at addr ffff800086c57970\n\n Call Trace:\n soft_cursor+0x378/0x6bc drivers/video/fbdev/core/softcursor.c:70\n bit_cursor+0xa90/0x1108 drivers/video/fbdev/core/bitblit.c:365\n fbcon_cursor+0x344/0x498 drivers/video/fbdev/core/fbcon.c:1427\n hide_cursor+0xdc/0x2d0 drivers/tty/vt/vt.c:883\n update_region+0x100/0x18c drivers/tty/vt/vt.c:669\n vcs_write+0x8ec/0xaf0 drivers/tty/vt/vc_screen.c:685\n\nbit_putcs_aligned() and bit_putcs_unaligned() already clamp the glyph\nindex to vc_font.charcount. Apply the same clamp in bit_cursor() after\nextracting the attribute and masking, before indexing fontdata.\n\nThe fix completes the bounds checking started in commit 18c4ef4e765a\n(\"fbdev: bitblit: bound-check glyph index in bit_putcs*\"), which missed\nthe cursor path.\n\nThis change should be safe because the clamp reuses the existing\ncontract from fbcon: charcount is maintained under console_lock in\ncon_font_set() and fbcon_font_set(), and hi_font_mask is cleared when\nswitching from 512 to 256 glyphs. When stale screen data with high bits\nremains after a font switch, or when vcs_write() stores an arbitrary\nvalue, clamping the index to 0 prevents the out-of-bounds read without\nchanging cursor

After use this buffer was never\nscrubbed which could lead to leaving for example clear key material in\nmemory which could be exposed via tricky reuse of this same memory.\n\nExtend the _ip_cprb_helper() function with another parameter 'scrub'\nused to steer scrubbing of this buffer. So now the caller has the\nopportunity to decide if scrubbing is needed or not.\n\nExtend the clear key to secure key token import process in function\ncca_clr2cipherkey() to tell the helper function from above to scrub\nthe cprb buffer when the clear key value is part of the request data.\n\nAdd explicit scrubbing on return from function cca_clr2cipherkey() for\nthe random EXOR buffer and the

resolved:\n\nsctp: validate stream count in sctp_process_strreset_inreq()\n\nWhen processing a RESET_IN_REQUEST from a peer,\nsctp_process_strreset_inreq() derives the stream count from the\nparameter length but does not check whether the resulting\nRESET_OUT_REQUEST would exceed SCTP_MAX_CHUNK_LEN.\n\nThe OUT request header (sctp_strreset_outreq, 16 bytes) is 8 bytes\nlarger than the IN request header (sctp_strreset_inreq, 8 bytes).\nGenerally, the IP payload is bounded to 65535 bytes, so the stream\nlist cannot be large enough to trigger the overflow. However, on\ninterfaces with MTU > 65535 (e.g., loopback with IPv6 jumbograms), a\nstream list that fits within the incoming IN parameter can cause a\n__u16 overflow in sctp_make_strreset_req() when computing the OUT\nrequest size, leading to an undersized skb allocation and a kernel\nBUG:\n\n net/core/skbuff.c:207 skb_panic\n net/core/skbuff.c:2625 skb_put\n net/sctp/sm_make_chunk.c:1535 sctp_addto_chunk\n net/sctp/sm_make_chunk.c:3695 sctp_make_strreset_req\n net/sctp/stream.c:655 sctp_process_strreset_inreq\n\nThe local setsockopt path validates the generated reset request size.\nHowever, for an incoming-only reset, it accounts for the smaller IN\nrequest even though the peer must generate an OUT request with the same\nstream list. Such a request cannot be completed successfully by the\npeer.\n\nReject peer IN requests whose corresponding OUT request would exceed\nSCTP_MAX_CHUNK_LEN. Also tighten the local check so it does not send an\nIN request that would require an oversized OUT request from the peer.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nsmb/client: handle overlapping allocated ranges in fallocate\n\nsmb3_simple_fallocate_range() can skip holes when an allocated range\nreturned by the server starts before the current fallocate offset. The\nskipped hole is not zero-filled, but fallocate still returns success. A\nlater write to that hole may therefore fail with ENOSPC.\n\nThe function queries allocated ranges so that it can preserve existing\ncontents and write zeroes only into holes. However, the server may return\na range that starts before the current fallocate offset.\n\nFor example, assume the fallocate request is [100, 400) and the only\nallocated range returned by the server is [0, 200):\n\n Request: [100, 400)\n Server range: [ 0, 200) allocated\n\n Correct:\n [100, 200) allocated data, skip\n [200, 400) hole, zero-fill\n\n Current:\n [100, 300) skipped\n [300, 400) zero-filled afterwards\n\nThe current code adds the full server range length, 200, to the current\noffset 100 and moves to 300. As a result, the hole in [200, 300) is\nskipped without being zero-filled.\n\nFix this by advancing only over the part of the allocated range that\noverlaps the current fallocate offset. Ignore ranges that end before the\ncurrent offset and reject ranges whose end offset overflows.\n\nThis also prevents a malformed range length from causing an out-of-bounds\nzero-buffer read.",

During device unregistration the device is\nunlisted from the ifindex hash before the NETDEV_UNREGISTER notifier\nchain runs, so a concurrent isotp_release() could find no device, skip\ncan_rx_unregister() entirely, and still proceed to free the socket.\nSince isotp_release() had already removed itself from the isotp\nnotifier list at that point, isotp_notify() would never get a chance to\nclean up either, leaving a stale CAN filter that keeps pointing at the\nfreed socket.\n\nFix this the same way raw.c already does: hold a tracked reference to\nthe bound net_device in the socket (so->dev/so->dev_tracker) from\nbind() onward instead of re-resolving it from the ifindex, and\nserialize bind()/release() with rtnl_lock() so that so->dev is always\nconsistent with what the NETDEV_UNREGISTER notifier sees. so->dev\nstays valid regardless of ifindex-hash unlisting, and is only ever\ncleared by whichever of isotp_release()/isotp_notify() gets there\nfirst, so the filter is always removed exactly once.\n\nisotp_bind() now rejects a (re)bind with -EAGAIN while so->[tx|rx].state\nisn't ISOTP_IDLE yet, so a timer left running by a prior\nNETDEV_UNREGISTER can't act on a newly bound so->ifindex.

data_ep_set_params() promotes ep->curpacksize to\nep->maxpacksize. However, maxsize is left at the original sample-rate\nderived value.\n\nSince u->buffer_size is allocated as maxsize * packets, the resulting\nDMA buffer is far too small for the requested transfer length. When the\nUSB host controller streams up to curpacksize bytes per packet, it writes\npast the end of the buffer via DMA, corrupting kernel heap memory.\n\nUpdate maxsize to curpacksize when fill_max is set so that the allocated\nDMA buffer size matches the actual transfer request size.\n\n[ changed to reassign maxsize only when ep->fill_max is set -- tiwai ]", "title": "Vulnerability description"

resolved:\n\nusb: gadget: f_midi: cancel pending IN work before freeing the midi object\n\nThe f_midi driver embeds a work item (midi->work) whose handler,\nf_midi_in_work(), dereferences the enclosing struct f_midi through\ncontainer_of(). This work is armed from two sites: f_midi_complete(),\non a normal IN-endpoint completion, and f_midi_in_trigger(), on an ALSA\nrawmidi output-stream start.\n\nNeither f_midi_disable() nor f_midi_unbind() cancels midi->work.\nf_midi_disable() only disables the endpoints and drains the in_req_fifo;\nit does not synchronize the work item, and the sound card is released\nasynchronously to the final free of the midi object.\n\nThe midi object is reference-counted (midi->free_ref) and is freed in\nf_midi_free() only once both the usb_function reference and the rawmidi\nprivate_data reference have been dropped. In f_midi_unbind(),\nf_midi_disable() runs before the sound card is released, so while the\nUSB endpoints are already disabled the rawmidi device is still usable by\nan open substream. A concurrent userspace write on such a substream can\nreach f_midi_in_trigger() and queue midi->work again after\nf_midi_disable() has returned. A work item armed this way may still be\npending when the last reference drops and f_midi_free() proceeds to\nkfree(midi), letting f_midi_in_work() dereference the struct after it\nhas been freed, a use-after-free.\n\nFor this reason cancelling midi->work in f_midi_disable() would not be\nsufficient: the ALSA trigger path can rearm the work after disable()\nreturns. Cancelling at the refcount-zero free site is the boundary\nafter which neither arming source can survive, because by then both\nreferences that keep the midi object alive have been dropped: the USB\nendpoints are already disabled and the rawmidi device has been released.\n\nFix this by calling cancel_work_sync(&midi->work) in the refcount-zero\nblock of f_midi_free(), before the embedded work_struct is freed along\nwith the rest of the structure. opts->lock is a sleeping mutex, so\ncalling cancel_work_sync() under it is permitted, and the handler takes\nmidi->transmit_lock rather than opts->lock, so no self-deadlock can\noccur while it waits for a running instance of the work to finish.\n\nThis issue was found by an in-house static analysis tool.", "title": "Vulnerability

with teardown\nduring netns destruction. If the netns refcount has already reached 0,\nget_net() performs a refcount_t increment on 0, triggering:\n\n refcount_t: addition on 0; use-after-free.\n\nAlthough rtnl_lock and bpf_devs_lock ensure the netdev pointer remains\nvalid, they cannot prevent the netns refcount from reaching zero.\n\nFix this by using maybe_get_net() instead of get_net(). maybe_get_net()\nuses refcount_inc_not_zero()

They differ once the device is\ncreated in or moved to a netns other than the one the request runs in.\nThe rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev),\nso a caller privileged there but not in vxlan->net can rewrite a vxlan\ndevice whose underlay lives in vxlan->net.\n\nvxlan_changelink() validates and applies the new configuration against\nvxlan->net (vxlan_config_validate(vxlan->net, ...)) and can reopen the\nunderlay socket in that netns, so the same reasoning as the tunnel\nchangelink series applies here.\n\nGate vxlan_changelink() with

users\ntreat ERR_PTR and NULL the same way.\nThis also causes a crash in the core dump logic, which is missing the\nERR_PTR check and ends up dereferencing it, as shown in the trace below.\n\nSwitch tracer creation to return NULL on failure only, so callers only\nneed a single NULL check.\n\n Internal error: Oops: 0000000096000006 [#1] SMP\n Modules linked in: mlx5_ib ib_uverbs ib_core ipv6

resolved:\n\nsctp: clear new_transport when removing a peer\n\nsctp_process_asconf_param() stores a newly added peer transport in\nasoc->new_transport. After all parameters in the ASCONF chunk have been\nprocessed, sctp_sf_do_asconf() uses this pointer to send a HEARTBEAT to the\nnew transport.\n\nAn authenticated ASCONF from a remote SCTP peer can add a transport and\nremove it again with a wildcard DEL-IP parameter in the same chunk. The\nwildcard deletion preserves the transport on which the ASCONF arrived, but\nremoves the newly added transport through\nsctp_assoc_del_nonprimary_peers(). The removal does not clear\nasoc->new_transport, leaving it pointing to the removed transport.\n\nsctp_sf_do_asconf() then creates a HEARTBEAT whose chunk->transport points\nto the removed transport without holding a transport reference. During\nlocal address replacement, src_out_of_asoc_ok keeps this HEARTBEAT on\ncontrol_chunk_list. After the transport is freed by RCU, a successful\nASCONF_ACK for the replacement address releases the queued HEARTBEAT and\nsctp_outq_select_transport() reads the freed transport's state.\n\nThe issue was found during a static audit of SCTP objects. With an\nauthenticated peer, the reproducer triggered the same KASAN report in 2\nof 2 unpatched runs on a KASAN-enabled netdev/main kernel:\n\n BUG: KASAN: slab-use-after-free in sctp_outq_select_transport\n Read of size 4 at addr ffff88800b9bd95c by task python3/197\n\n Call Trace:\n sctp_outq_select_transport+0x549/0x8b0 [sctp]\n sctp_outq_flush+0x306/0x2c60 [sctp]\n sctp_transport_immediate_rtx+0xaf/0x260 [sctp]\n sctp_process_asconf_ack+0xa48/0xf70 [sctp]\n\n Allocated by task 197:\n sctp_transport_new+0x68/0x650 [sctp]\n sctp_assoc_add_peer+0x258/0x12a0 [sctp]\n sctp_process_asconf+0x5e9/0x1090 [sctp]\n\n Last potentially related work creation:\n __call_rcu_common.constprop.0+0x77/0xb70\n sctp_assoc_del_nonprimary_peers+0x7c/0xd0 [sctp]\n sctp_process_asconf+0xd9c/0x1090 [sctp]\n\nThe first invalid access was a four-byte read of transport->state at\nnet/sctp/outqueue.c:833.

it simply skips creation when *bo_ptr is non-NULL.\nBut it unconditionally reserves, pins, gart allocates\nand maps the BO afterwards.\n\nWhen the same non-NULL BO pointer is passed in again,\nfor example firmware buffers that live in adev and are\nre-loaded on every resume / cp_resume / start\nunder AMDGPU_FW_LOAD_DIRECT, amdgpu_bo_pin() just increases\npin_count unconditionally, however the matching teardown only unpins\nonce, so pin_count never drops to zero, so TTM is not able\nto move, swap or evict a BO, causing BO leaks.\n\nThis commit fixes this issue by only pinning the bo\nonce at creation, and repeated calls no longer\ntake additional pin references.\n\n(cherry picked from commit 3ddc0ae76202c447b6aec61e907b852bc94671cf)", "title": "Vulnerability description" } ],

allocation; it does not bound it to\nCEPH_PG_MAX_SIZE. The helper backs both pg_temp and pg_upmap decoding, and\napply_upmap()/get_temp_osds() later copy the decoded list into the fixed-size\non-stack array struct ceph_osds.osds[CEPH_PG_MAX_SIZE]. A monitor that sends\nan OSDMap with a pg_temp/pg_upmap entry longer than 32 thus causes a stack\nout-of-bounds write.\n\nAn OSD set for a single PG can never exceed CEPH_PG_MAX_SIZE, so reject longer\nentries at decode time. The bound is well below the old overflow threshold, so\nit also covers the allocation-size overflow the previous check guarded against.\n\n BUG: KASAN: stack-out-of-bounds in

"description", "text": "In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: jz4780: Cache host clock rate at probe to prevent CCF prepare_lock deadlock\n\nFix a severe AB/BA deadlock between the Common Clock Framework (CCF)\nand the I2C adapter lock, which triggers when an I2C-controlled clock\ngenerator client (like the Si5351) is registered or modified under the CCF.\n\nDuring an i2c client clock (generator) frequency change, the CCF acquires its global\n'prepare_lock' mutex and the driver calls i2c_transfer() to update the client's\nchip registers, stalling for the adapter's I2C bus lock.\n\nConcurrently, an independent, parallel transfer on the same bus (e.g., a GPIO\nexpander handling LEDs) can hold the I2C adapter lock. Inside this parallel\ntransfer path, jz4780_i2c_set_speed() calls clk_get_rate() on the host\ncontroller's input clock to calculate bus timings. This call attempts to acquire\nthe blocked CCF 'prepare_lock', creating a circular dependency that freezes\nthe system.\n\nThe jz4780 host controller clock itself is static and never changes at runtime.\n\nHowever, calling clk_get_rate() inside the active transfer path introduces\nan unnecessary dependency on the CCF internal locks.\n\nEliminate this synchronous clk_get_rate() call from the active transfer\npath by caching the static host peripheral clock rate once - inside the private\njz4780_i2c structure during jz4780_i2c_probe(). Update jz4780_i2c_set_speed()\nto use this cached value, safely decoupling active I2C transactions from the\nCCF internal locks without any risk of stale timings.\n\nAssisted-by web based Google AI

resolved:\n\nnet/9p: fix infinite loop in p9_client_rpc on fatal signal\n\nWhen p9_client_rpc() is called with type P9_TFLUSH and the transport\nhas no peer (e.g. fd transport backed by pipes with no 9p server),\na fatal signal causes an infinite loop:\n\n again:\n\terr = io_wait_event_killable(req->wq, ...)\n\t/* SIGKILL wakes the task, returns -ERESTARTSYS */\n\n\tif (err == -ERESTARTSYS && c->status == Connected &&\n\t\ttype == P9_TFLUSH) {\n\t\tsigpending = 1;\n\t\tclear_thread_flag(TIF_SIGPENDING);\n\t\tgoto again;\n\t}\n\nclear_thread_flag() clears TIF_SIGPENDING before jumping back to\nio_wait_event_killable(). signal_pending_state() checks TIF_SIGPENDING,\nfinds it zero, and the task goes to sleep again. The task can only wake\non the next signal delivery that calls signal_wake_up() and sets\nTIF_SIGPENDING again. When that happens the loop repeats, clears\nTIF_SIGPENDING, and sleeps again indefinitely.\n\nThis is triggered in practice by coredump_wait(): when a thread in a\nmulti-threaded process causes a coredump (e.g. via SIGSYS from Syscall\nUser Dispatch), coredump_wait() sends SIGKILL to all other threads and\nwaits for them to call mm_release(). If one of those threads is blocked\nin p9_client_rpc() over an fd transport with no peer, it enters the\nP9_TFLUSH loop and never calls mm_release(), so coredump_wait() stalls\nforever:\n\nINFO: task syz.0.18:676 blocked for more than 143 seconds.\n Not tainted 6.12.77+ #1\ntask:syz.0.18 state:D stack:27600 pid:676 tgid:673 ppid:630 flags:0x00000004\nCall Trace:\n \n context_switch kernel/sched/core.c:5344 [inline]\n __schedule+0xcb4/0x5d50 kernel/sched/core.c:6724\n __schedule_loop kernel/sched/core.c:6801 [inline]\n schedule+0xe5/0x350 kernel/sched/core.c:6816\n schedule_timeout+0x253/0x290 kernel/time/timer.c:2593\n do_wait_for_common kernel/sched/completion.c:95 [inline]\n __wait_for_common+0x409/0x600 kernel/sched/completion.c:116\n wait_for_common kernel/sched/completion.c:127 [inline]\n wait_for_completion_state+0x1d/0x40 kernel/sched/completion.c:264\n coredump_wait fs/coredump.c:448 [inline]\n do_coredump+0x854/0x4350 fs/coredump.c:629\n get_signal+0x1425/0x2730 kernel/signal.c:2903\n arch_do_signal_or_restart+0x81/0x880 arch/x86/kernel/signal.c:337\n exit_to_user_mode_loop kernel/entry/common.c:111 [inline]\n exit_to_user_mode_prepare include/linux/entry-common.h:328 [inline]\n __syscall_exit_to_user_mode_work kernel/entry/common.c:207 [inline]\n syscall_exit_to_user_mode+0xf9/0x160 kernel/entry/common.c:218\n do_syscall_64+0x102/0x220 arch/x86/entry/common.c:84\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\n \n\nFix: check fatal_signal_pending() before clearing TIF_SIGPENDING in the\nP9_TFLUSH retry loop. At that point TIF_SIGPENDING is still set, so\nfatal_signal_pending() works correctly. If a fatal signal is pending,\njump to recalc_sigpending to restore TIF_SIGPENDING and return\n-ERESTARTSYS to the caller.\n\nThe same defect is present in stable kernels back to 5.4. On those\nkernels the infinite loop is broken earlier by a second SIGKILL from\nthe parent process (e.g. kill_and_wait() retrying after a timeout),\nresulting in a zombie process and a shutdown delay rather than a\npermanent D-state hang, but the underlying flaw is the same.\n\nFound by Linux Verification Center (linuxtesting.org) with Syzkaller.", "title": "Vulnerability description" } ],

resolved:\n\nmm/ptdump: always stabilise against page table freeing using init_mm\n\nPrevious commits have established the invariant that kernel page table\nfreeing is performed while an mmap read lock on init_mm is held, which\nfixes races between ptdump and kernel page table freeing over init_mm.\n\nHowever, x86 and arm64 can perform a ptdump over an mm other than init_mm\nvia ptdump_walk_pgd() and since kernel memory ranges are shared across\nnon-kernel mm's, this means that the race still exists for these cases.\n\nFix this by acquiring a nested mmap write lock for init_mm in\nptdump_walk_pgd().\n\nThis is safe as we take this after mmap write locking the mm, and nothing\nacquires the init_mm lock first before locking an arbitrary mm, so no\ndeadlock is possible.\n\nAlso update walk_page_range_debug() to assert that init_mm is write\nlocked, add a comment explaining why and remove some redundant code, and\neliminate the unnecessary and confusing invocation of\nwalk_kernel_page_table_range().\n\nWe can safely remove the non-NULL check for walk.mm, as the mmap lock\nasserts would NULL pointer deref if it was (and of course no callers do\nthis).\n\nThe first point at which ptdump can race kernel page table freeing is\ncommit b6bdb7517c3d (\"mm/vmalloc: add interfaces to free unmapped page\ntable\"), so we target this in the Fixes

The v3 fix rounds alloc_len up with ALIGN() before deriving the\ndescriptor count:\n\n\trep_max_zones = (ALIGN((u64)alloc_len, RZONES_DESC_HD) -\n\t\t\t RZONES_DESC_HD) >> ilog2(RZONES_DESC_HD);\n\tarr_len = (u64)RZONES_DESC_HD * (rep_max_zones + 1);\n\nFor alloc_len in 0xFFFFFFC1..0xFFFFFFFF, ALIGN() rounds up to\n0x100000000, so arr_len is 4 GB. On 32-bit, kzalloc()'s size_t is 32-bit\nand truncates 0x100000000 to 0; kzalloc(0) returns ZERO_SIZE_PTR, which\npasses the !arr check, and desc = arr + 64 is then dereferenced in the\nloop -> out-of-bounds write / panic.\n\nClamp rep_max_zones to devip->nr_zones. The loop already stops at\nsdebug_capacity (after nr_zones zones), so a report can never hold more\nthan nr_zones descriptors; the clamp does not change the report, it only\nbounds arr_len to

resolved:\n\nInput: evdev - sanitize event type index when fetching event masks\n\nThe user-supplied event type index passed to EVIOCGMASK / EVIOCSMASK\nioctls is used to index the static counts array in evdev_get_mask_cnt()\nand client evmasks array in evdev_get_mask().\n\nWhile the event type is architecturally bounded by EV_CNT, speculative\nexecution may mispredict bounds checks and perform out-of-bounds loads.\n\nSanitize the event type index in evdev_get_mask_cnt() branchlessly using\narray_index_mask_nospec(). This clamps the index to 0 for safe array\naccess and forces the returned count to 0 speculatively when the index\nis out of bounds.\n\nWe do not need additional array_index_nospec() calls in evdev_get_mask()\nbecause evdev_get_mask_cnt() speculatively forces the count (and\nresulting xfer_size) to 0 for out-of-bounds types, preventing any\nspeculative memory access to client evmasks

signed int, so a small device-advertised bulk-OUT max_transfer\nmakes buf_end negative. The loop guard then compares the u32\nurb->transfer_buffer_length against that negative int: the usual\narithmetic conversion turns buf_end into a large unsigned value, so the\nguard stays true and each iteration keeps appending SysEx framing and\npayload bytes past the end of the URB transfer buffer, which is only\nmax_transfer bytes long.\n\nA USB device that advertises a tiny bulk-OUT endpoint can therefore\ntrigger an attacker-length- and content-controlled heap out-of-bounds\nwrite when a process writes to the created /dev/snd/midiC*D* node.\n\nReturn early when there is no room for even one SysEx, so the loop is\nnever entered with a bound that would wrap.

receives an event (such as incoming data), the call gets placed\non the socket's queue and a thread in recvmsg can be awakened to go and\nprocess it. Once the thread has picked up the call off of the queue,\nfurther events will cause it to be requeued, and once the socket lock is\ndropped (recvmsg uses call->user_mutex to allow the socket to be used in\nparallel), a second thread can come in and its recvmsg can pop the call off\nthe socket queue again.\n\nIn such a case, the first thread will be receiving stuff from the call and\nthe second thread will be blocked on call->user_mutex. The first thread\ncan, at this point, process both the event that it picked call for and the\nevent that the second thread picked the call for and may see the call\nterminate - in which case the call will be \"released\", decoupling the call\nfrom the user call ID assigned to it (RXRPC_USER_CALL_ID in the control\nmessage).\n\nThe first thread will return okay, but then the second thread will wake up\nholding the user_mutex and, if it sees that the call has been released by\nthe first thread, it will BUG thusly:\n\n\tkernel BUG at net/rxrpc/recvmsg.c:474!\n\nFix this by just dequeuing the call and ignoring it if it is seen to be\nalready released.

outer ICMP packet to the\nquoted original request before passing it to icmp_send(). However,\nIPCB(skb)->opt still describes the outer IPv4 header.\n\nA timestamp option in the outer header can therefore leave an offset\nthat points into the quoted transport header after the rebase.\n__ip_options_echo() treats a byte at that stale location as the option\nlength and copies it into the fixed-size option storage on the\n__icmp_send() stack, causing a stack out-of-bounds write.\n\nClear the stale option metadata after resetting the network header.\nKeep the remaining control block fields, including the ingress\ninterface used by the ICMP response path.", "title":

Since the page reuse strategy was added, a cleaned RX buffer\nkeeps its page (and its DMA mapping) in the ring for reuse, and refill\nis batched: aq_ring_rx_fill() returns early until AQ_CFG_RX_REFILL_THRES\nslots are free. Slots that were consumed but not yet reposted therefore\nsit in the complementary [sw_tail, sw_head) gap with a live page, and\nthe deinit walk never visits them: up to a refill batch worth of pages\nand DMA mappings leak on every interface down.\n\nWalk the whole ring instead and release whatever is still there.

resolved:\n\nwifi: brcmfmac: drain bus_reset work on device removal\n\nbrcmf_fw_crashed() and the debugfs \"reset\" entry both schedule\ndrvr->bus_reset, whose callback recovers drvr through container_of()\nand dereferences it. The removal path frees drvr (brcmf_free ->\nwiphy_free) without draining the work, so a bus_reset callback pending\nor running during removal can outlive drvr.\n\nCancellation cannot live in brcmf_detach() or brcmf_free(): the work\ncallback reaches teardown through the bus .reset op (PCIe\nbrcmf_pcie_reset -> brcmf_detach; SDIO brcmf_sdio_bus_reset ->\nbrcmf_sdiod_remove -> brcmf_free), so cancelling there would wait for\nthe running work and deadlock.\n\nAdd a per-bus mutex (bus_reset_lock) and route all arming through\nbrcmf_bus_schedule_reset(), which under the lock skips when the bus is\nmarked removing. Each bus remove entry calls\nbrcmf_bus_cancel_reset_work(), which under the same lock sets removing\nand cancels the work. Holding the mutex across cancel_work_sync() makes\nthe set-removing + drain step atomic. Every producer reaches the arming\npath from process context -- the PCIe firmware-halt notification runs in\nthe threaded IRQ handler (brcmf_pcie_isr_thread) and the SDIO hostmail\npath runs from the data workqueue -- so the mutex is taken only in\nsleepable contexts. Where applicable the remove entry first stops the\nfirmware-crash producer: on PCIe mask the mailbox and synchronize_irq;\non SDIO unregister the bus interrupt and cancel the data worker, which\nalso reports firmware halts through brcmf_fw_crashed(). The mutex is\ninitialized at bus allocation. The SDIO suspend power-off path frees\ndrvr through the same brcmf_sdiod_remove() and takes the same lock;\nresume re-allows the work only on a successful re-probe.\n\nAlso guard brcmf_fw_crashed() against a NULL bus_if/drvr: it can fire\nbefore brcmf_attach() wires up drvr, and it dereferences drvr\n(bphy_err/brcmf_dev_coredump) before reaching the arming gate.\n\nThe bus_reset work is shared across buses, so the drain is applied to\nevery remove path: PCIe (the .reset op introduced by the Fixes commit),\nSDIO (arms the same work through brcmf_fw_crashed()), and USB (via the\ndebugfs \"reset\" entry). cancel_work_sync() drains a running or pending\nbus_reset work item before removal frees drvr, and patch 1/2 makes the\nscratch-buffer release safe when reset teardown has already released\nthose DMA buffers.\n\nThis patch fixes the lifetime of the bus_reset work item itself. It does\nnot attempt to address the separate, pre-existing lifetime of the\nasynchronous firmware completion started by the PCIe reset path. That\ncallback needs its own lifetime/ownership protocol and is being tracked\nseparately.\n\nThis issue was found by an in-house static analysis tool.", "title": "Vulnerability description" } ],

resolved:\n\nusb: gadget: f_tcm: synchronize delayed set_alt with teardown\n\nThe f_tcm set_alt() path defers endpoint setup to a work item and\ncompletes the delayed status response from process context. The delayed\nwork uses f_tcm private state and may complete the setup request after\ndisconnect or function teardown has already moved on.\n\nCancel and drain the delayed set_alt work when the function is unbound or\nfreed. For disable paths, which are reached under the composite device\nlock, use a small state machine and a non-sleeping cancellation path\ninstead of cancel_work_sync(). If the work is already running, mark it\ncancelled and let the worker own the cleanup; otherwise tcm_disable() can\ncancel the queued work and clean up immediately.\n\nAlso serialize the final delayed-status completion with the cancellation\ncheck while holding the composite device lock. This prevents a disconnect\nfrom clearing delayed_status while the worker is about to complete the\ncontrol request.\n\nValidation reproduced this kernel report:\nBUG: KASAN: slab-use-after-free in

in the USB\nfirmware-download path.\n\nFix this memory leak by calling release_firmware() immediately after\nlbs_fw_loaded() returns.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nthe current wireless tree.\n\nAn x86_64 allyesconfig build showed no new warnings.

resolved:\n\nmedia: rtl2832_sdr: Return queued buffers on start_streaming() failure\n\nThe vb2 framework hands buffers to the driver via buf_queue() before\ncalling start_streaming(). If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\nrtl2832_sdr_start_streaming() had multiple error paths that hit this\ntrap: two direct early returns (-ENODEV, -ERESTARTSYS), plus six\n`goto err` paths covering subdev s_power, tuner setup, ADC setup,\nstream-buffer allocation, urb allocation, and urb submission failures.\nNone of them returned the queued buffers.\n\nThe original function had no distinct success exit and fell straight\nthrough into the err label, which previously only did mutex_unlock and\n\"return ret\". Adding queued-buffer cleanup at err must therefore be\npaired with an explicit success return; otherwise every successful\nstart would also drain the buffer queue and kill streaming. Add that\nsuccess return, then add rtl2832_sdr_cleanup_queued_bufs() at the err\nlabel and before each early return.\n\nThe cleanup helper takes a vb2_buffer_state argument so that the\nstart_streaming error paths can pass VB2_BUF_STATE_QUEUED (as\nexpected by userspace on start_streaming failure) while stop_streaming\nkeeps its existing VB2_BUF_STATE_ERROR semantics.\n\nThis mirrors the uvcvideo fix in commit 4cf3b6fd54eb (\"media: uvcvideo:\nReturn queued buffers on start_streaming() failure\").\n\nThe err label still does not roll back power_ctrl(), frontend_ctrl(),\nthe POWER_ON flag, or stream/URB allocations that may have happened\nbefore the failing step. Those are pre-existing leaks of a different\nclass and are not addressed here.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nigbvf: Fix leak in TX DMA error cleanup\n\nIf an error is encountered while mapping TX buffers, the driver should\nunmap any buffers already mapped for that skb.\n\nBecause count is incremented before each frag mapping, it will always\nmatch the correct number of unmappings needed when dma_error is reached.\nDecrementing count before the while loop in dma_error causes an\noff-by-one error. If any mapping was successful before an unsuccessful\nmapping, exactly one DMA mapping (the head) would leak.\n\nThis bug was introduced by a 2010 fix for an endless loop in dma_error.\nAll other

whole machine:\n\n NETDEV WATCHDOG: ens6f1 (qede): transmit queue 2 timed out 10226 ms\n [qede_tx_timeout:586(ens6f1)]TX timeout on queue 2!\n [qede_recovery_handler:2665(ens6f0)]Starting a recovery

This keeps the old gating exactly: a device that was down\nor a failed recovery returns false, as those paths never reached the\nudp_tunnel_nic_reset_ntf() call before either.\n\nThis was the only

When the malformed parameter is last in an INIT, the read\nstarts at the receive skb tail, and the value is copied into the state\ncookie returned in the INIT ACK.

skb->data[0].\nA connected HIDP peer can reply with only a DATA transaction header,\nleaving the skb empty after the header is removed.\n\nKMSAN reports an uninitialized-value use in hidp_session_run(), with the\nvalue originating in __alloc_skb() through vhci_write(). The transaction\nheader checks remove the empty-frame reports, but this report remains until\nthe payload check is added.\n\nThe comparison can also consume a peer-controlled byte beyond the declared\nL2CAP PDU. A DATA | FEATURE response followed by an extra 0x01 byte made\nthe current code accept that byte as report ID 1 and complete\nHIDIOCGFEATURE with a zero-byte result. With this change the malformed\nresponse is rejected with -EIO, while a subsequent valid response still\nsucceeds.\n\nRequire a payload byte before comparing a numbered report ID.

resolved:\n\ncan: bcm: fix CAN frame rx/tx statistics\n\nKCSAN detected a data race within the bcm_rx_handler() when two CAN frames\nhave been simultaneously received and processed in a single rx op by two\ndifferent CPUs.\n\nUse atomic operations with (signed) long data types to access the\nstatistics in the hot path to fix the KCSAN complaint.\n\nAdditionally simplify the update and check of statistics overflow by\nusing the atomic operations in separate bcm_update_[rx|tx]_stats()\nfunctions. The rx variant runs under bcm_rx_update_lock to prevent\nraces when resetting the two rx counters; the tx variant runs under\nbcm_tx_lock and only needs to guard its own counter's overflow.\n\nAs the rx path resets its values already at LONG_MAX / 100, there is\nno conflict between the two locking domains (bcm_rx_update_lock vs.\nbcm_tx_lock) even for ops that use both paths.\n\nThe rx statistics update and the frames_filtered update in\nbcm_rx_changed() were previously performed in two separate\nbcm_rx_update_lock sections. For an rx op subscribed on all interfaces\n(ifindex == 0), bcm_rx_handler() can run concurrently on different\nCPUs, so a counter reset by one CPU between these two sections could\nleave frames_filtered larger than frames_abs on another CPU, producing\na bogus (even negative) reduction percentage in procfs. Update the\nstatistics in the same critical section as bcm_rx_changed() to close\nthis gap, which also removes the now unneeded extra lock/unlock pair\naround the traffic_flags calculation.", "title":

When reset teardown\nhas run before removal, remove's own teardown would call\ndma_free_coherent() a second time on the already-freed DMA allocation.\n\nNULL the pointers after free, matching release_ringbuffers(), so a later\nrelease observes that the allocation has already been released.

resolved:\n\nscsi: target: Bound PR-OUT TransportID parsing to the received buffer\n\ncore_scsi3_decode_spec_i_port() and core_scsi3_emulate_register_and_move()\nhand the raw PERSISTENT RESERVE OUT parameter buffer to\ntarget_parse_pr_out_transport_id() without telling it how many bytes are\nvalid. For an iSCSI TransportID (FORMAT CODE 01b),\niscsi_parse_pr_out_transport_id() locates the \",i,0x\" ISID separator with\nan unbounded strstr() (and on the error path prints the name with a further\nunbounded \"%s\"). An initiator can submit a TransportID whose iSCSI name\ncontains neither a \",i,0x\" substring nor a NUL terminator, filling the\nparameter list to its end, so the scan runs off the end of the buffer.\n\nWhen the parameter list spans more than one page the buffer is a multi-page\nvmap (transport_kmap_data_sg()), so the over-read walks into the trailing\nvmalloc guard page and oopses (KASAN: vmalloc-out-of-bounds in strstr). It\nis reachable by any fabric that delivers a PR OUT to a device exported\nthrough an iSCSI TPG, including a guest via vhost-scsi.\n\nPass the number of received bytes down to the parser and validate the iSCSI\nTransportID's own self-described length (ADDITIONAL LENGTH + 4) once, up\nfront: reject it if it is below the spc4r17 minimum or larger than the\nreceived buffer, then bound the separator search, the ISID walk and the\nname copy by that length. This is the length check the callers already\nperform after the parse (core_scsi3_decode_spec_i_port() compares tid_len\nagainst tpdl, core_scsi3_emulate_register_and_move() validates it against\ndata_length), moved ahead of the scan. Also drop the unbounded \"%s\" of the\nunterminated name.\n\nAdd per-format explicit name-length checks before copying into i_str,\nrather than silently truncating with min_t: for FORMAT CODE 00b reject if\nthe descriptor body (tid_len - 4 bytes) cannot fit in\ni_str[TRANSPORT_IQN_LEN]; for FORMAT CODE 01b reject if the name portion\n(from &buf[4] up to the separator) cannot fit. Both checks make the bounds\nintent explicit at each format branch.\n\nWhile here, also reject a FORMAT CODE 01b TransportID whose \",i,0x\"\nseparator sits at the very end of the descriptor: that leaves an empty ISID\nand points the returned port nexus pointer at buf + tid_len, one past the\ndescriptor, which the registration code (__core_scsi3_locate_pr_reg(),\n__core_scsi3_alloc_registration()) then dereferences as the ISID string --\nthe same over-read of the parameter buffer for a malformed descriptor.", "title":

If start_streaming() returns an error\nwithout first returning those buffers via vb2_buffer_done(),\nvb2_start_streaming() fires WARN_ON(owned_by_drv_count) and the queued\nbuffers leak.\n\npwc's start_streaming() had two early returns that hit this trap:\n-ENODEV when the USB device was already disconnected, and -ERESTARTSYS\nwhen mutex_lock_interruptible() was interrupted by a signal. Call the\nexisting pwc_cleanup_queued_bufs() helper with VB2_BUF_STATE_QUEUED\nbefore returning (matching the state already used by the\npwc_isoc_init() error path in the same function).\n\nThis

resolved:\n\nipv4: igmp: Fix potential UAF in igmp_gq_start_timer()\n\nA race condition exists between device teardown (inetdev_destroy) and\nincoming IGMP query processing (igmp_rcv), leading to a Use-After-Free\nin the IGMP timer callback.\n\nDuring device destruction, inetdev_destroy() drops the primary reference\nto in_device, which can drop its refcount to 0. The actual freeing of\nin_device memory is deferred via RCU (using call_rcu()).\n\nConcurrently, igmp_rcv() runs under RCU read lock and obtains the\nin_device pointer. Because the memory is RCU-protected, CPU-0 can safely\ndereference in_device even if its refcount has hit 0.\n\nHowever, if CPU-0 calls igmp_gq_start_timer() and re-arms the timer, it\nattempts to acquire a reference using in_dev_hold(). This increments the\nrefcount from 0 to 1, triggering a \"refcount_t: addition on 0\" warning.\nSince the in_device memory is still scheduled to be freed after the RCU\ngrace period (as the free callback does not check the refcount again),\nthe device is freed while the timer is still armed. When the timer\nexpires, it accesses the freed memory, causing a kernel panic.\n\nFix this by using refcount_inc_not_zero() (via a new helper\nin_dev_hold_safe()) to prevent acquiring a reference if the device is\nalready being destroyed. If the refcount is 0, we do not arm the timer.\n\nA similar issue in IPv6 MLD is fixed in a subsequent patch.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\nnet: thunderbolt: Fix frags[] overflow by bounding frame_count\n\ntbnet_poll() assembles a multi-frame ThunderboltIP packet into one skb. The\nfirst frame goes into the skb linear area and every further frame is added as\na page fragment.\n\n\tskb_add_rx_frag(skb, skb_shinfo(skb)->nr_frags,\n\t\t\tpage, hdr_size, frame_size,\n\t\t\tTBNET_RX_PAGE_SIZE - hdr_size);\n\nA packet of frame_count frames therefore ends up with frame_count - 1\nfragments. tbnet_check_frame() only bounds the peer supplied frame_count to\nTBNET_RING_SIZE / 4 (64), which is far above MAX_SKB_FRAGS (17 by default). A\npeer that sends a packet of 19 or more small frames pushes nr_frags past\nMAX_SKB_FRAGS, so skb_add_rx_frag() writes past skb_shinfo()->frags[] and\ncorrupts memory after the shared info.\n\nTighten the start of packet bound to MAX_SKB_FRAGS + 1 so a packet can never\nproduce more fragments than frags[] can hold. This matches the recent skb\nfrags overflow fixes in other receive paths, for example f0813bcd2d9d (\"net:\nwwan: t7xx: fix potential skb->frags overflow in RX path\") and 600dc40554dc\n(\"net: usb:

processes incoming URB data byte by byte.\nHowever, it fails to check if the `read_pos` index exceeds\nIMS_PCU_BUF_SIZE.\n\nIf a malicious USB device sends a packet larger than IMS_PCU_BUF_SIZE,\n`read_pos` will increment indefinitely. Moreover, since `read_pos` is\nlocated immediately after `read_buf`, the attacker can overwrite\n`read_pos` itself to arbitrarily control the index.\n\nThis manipulated `read_pos` is subsequently used in\n`ims_pcu_handle_response()` to copy data into `cmd_buf`, leading to a\nheap buffer overflow.\n\nSpecifically, an attacker can overwrite the `cmd_done.wait.head` located\nat offset 136 relative to `cmd_buf` in the `ims_pcu_handle_response()`.\nConsequently, when the driver calls `complete(&pcu->cmd_done)`, it\ntriggers a control flow hijack by using the manipulated pointer.\n\nFix this by adding a bounds check for `read_pos` before writing to\n`read_buf`. If the packet is too long, discard it, log a warning,\nand reset the parser state.\n\n[dtor: factor out resetting packet state, reset checksum as well]", "title": "Vulnerability description" } ],

resolved:\n\nperf/core: Fix group leader use-after-free after sibling detach\n\nperf_group_detach() handles leader and sibling detach differently. When the\ngroup leader is detached, all siblings are promoted to singleton events and\ntheir group_leader pointer is reset to themselves. When a sibling is\ndetached, it is removed from the leader's sibling_list, but its\ngroup_leader pointer is left pointing at the old leader.\n\nThat is harmless when the sibling is being closed and freed immediately, as\nin the DETACH_DEAD path. It is not safe when the sibling is detached but\nkept alive, such as during CPU hotplug with DETACH_GROUP. In that case the\nsibling is removed from the context, while its file descriptor can still\nkeep it alive.\n\nA typical failing sequence is:\n\n - A group contains leader L and sibling S.\n - CPU hot-unplug detaches S with DETACH_GROUP, removing it from\n L->sibling_list but leaving S->group_leader == L.\n - L is later closed and freed.\n - A PERF_IOC_FLAG_GROUP ioctl on S follows S->group_leader and\n dereferences the freed leader.\n\nThis was reproduced by running the perf event fuzzer, CPU hotplug, and a\nstress workload concurrently:\n\n Unable to handle kernel paging

resolved:\n\ncan: isotp: serialize TX state transitions under so->rx_lock\n\nThe TX state machine (so->tx.state) is driven from three contexts:\nsendmsg() claiming and progressing a transfer, the RX path consuming\nFlow Control/echo frames, and two hrtimers timing out a stalled\ntransfer. Mixing a lock-free cmpxchg() claim in sendmsg() with\nhrtimer_cancel() calls made under so->rx_lock elsewhere left windows\nwhere a frame or timer callback could act on a state that had already\nmoved on, corrupting an unrelated transfer.\n\nso->rx_lock now covers the full lifecycle of a TX claim: sendmsg()\ntakes it to check so->tx.state is ISOTP_IDLE, switch it to\nISOTP_SENDING, bump so->tx_gen and drain the previous transfer's\ntimers - all as one critical section. isotp_rcv_fc()/isotp_rcv_cf()\nalready run under this lock via isotp_rcv(), and isotp_rcv_echo() now\ntakes it itself, so none of them can ever observe a transfer mid-claim.\nThis also means a transfer can no longer be handed to sendmsg()'s\ncleanup paths (signal or send error) while another thread is\nconcurrently claiming or finishing it, so those paths can cancel\ntimers and reset the state unconditionally.\n\nisotp_release() claims the socket the same way, so a racing sendmsg()\nsees a consistent ISOTP_SHUTDOWN and skips arming its timer or sending.\n\nOnly the hrtimer callbacks stay outside so->rx_lock, since they run\nunder so->rx_lock's cancellation elsewhere and taking it themselves\nwould deadlock. so->tx_gen lets them recognize whether the transfer\nthey timed out is still the one currently active, so they don't\nreport an error against a transfer that has since completed or been\nsuperseded.",

resolved:\n\nsctp: fix use-after-free of cached ASCONF chunk\n\naddip_last_asconf caches the outstanding outbound ASCONF chunk. The normal\nASCONF-ACK completion path releases the chunk and clears the pointer.\n\nHowever, sctp_asconf_queue_teardown() releases the cached chunk without\nclearing addip_last_asconf. During peer restart handling,\nsctp_sf_do_dupcook_a() queues SCTP_CMD_PURGE_ASCONF_QUEUE, which invokes\nsctp_asconf_queue_teardown() while the association remains alive and leaves\nthe pointer dangling.\n\nA delayed authenticated ASCONF-ACK can then reach sctp_sf_do_asconf_ack(),\nwhich accesses the stale chunk and passes it to sctp_process_asconf_ack(),\ncausing a use-after-free and a second release.\n\nClearing the pointer exposes a race with T4 expiry. Peer restart handling\nqueues the timer stop before the purge, but SCTP_CMD_TIMER_STOP uses\ntimer_delete(), which does not wait for a callback already running on\nanother CPU. Such a callback can reach sctp_sf_t4_timer_expire() after\nthe purge and dereference NULL.\n\nClear addip_last_asconf after releasing the cached chunk, and make\nsctp_sf_t4_timer_expire() consume a

icmpv6_send().\nThe clone still carries the outer packet's inet6_skb_parm in skb->cb.\n\nIf the outer packet had a Home Address Option, IP6CB(skb2)->dsthao\nremains non-zero after skb_pull(). icmpv6_send() later calls\nmip6_addr_swap(), which uses that stale dsthao offset against the quoted\ninner packet. A malformed inner destination-options header can then make\nthe HAO lookup and address swap run past the end of the quoted packet\nand corrupt skb_shared_info.\n\nClear skb2->cb[] before pulling the

PPPoE subsequently writes\nsix bytes through the stale pointer into the freed head.\n\nReload the PPPoE header through the skb's network-header offset after\ndevice header creation. pskb_expand_head()

If xfs_iread_extents() fails, the function returns\nimmediately without releasing the lock, leaking the quota inode ILOCK.\nThis can leave the quota inode locked and cause subsequent quota\noperations

resolved:\n\nlibceph: fix multiple unsafe decodes in decode_locker()\n\ndecode_locker() in cls_lock_client.c contains three unsafe decode\noperations that allow a malicious or compromised OSD to trigger\nslab-out-of-bounds reads:\n\n1. ceph_decode_copy() at the locker_id_t name field has no preceding\n bounds check. With p == end after ceph_start_decoding() accepts\n struct_len=0, this reads sizeof(ceph_entity_name) = 9 bytes past\n the validated buffer boundary.\n\n2. *p += sizeof(struct ceph_timespec) after the locker_info_t header\n is an unchecked pointer advance. A malicious OSD can position p\n past end, causing all subsequent _safe checks to pass against a\n bogus boundary.\n\n3. len = ceph_decode_32(p) has no preceding bounds check, and the\n immediately following *p += len is uncapped. A malicious OSD can\n send len=0xffffffff, advancing p gigabytes past end and escaping\n the decode window entirely.\n\nFix all three by replacing bare operations with their safe variants:\n ceph_decode_copy -> ceph_decode_copy_safe\n *p += sizeof(...) -> ceph_decode_skip_n\n ceph_decode_32(p) -> ceph_decode_32_safe\n *p += len -> ceph_decode_skip_n\n\nA new label is added to return -EINVAL on any bounds violation.\n-EINVAL is appropriate here: the data received from the OSD\nis structurally malformed, which is an invalid argument to the decode\ncontract regardless of whether the caller or the wire is at fault.\n\nAttacker model: a malicious or compromised OSD in a multi-tenant Ceph\ndeployment can trigger this against any kernel client that issues the\nlock.get_info class method (e.g. during RBD exclusive lock acquisition)\nwithout any further privileges beyond OSD session establishment.\n\n[ idryomov: use ceph_decode_skip_string() to skip description, trim\n changelog

resolved:\n\nlibceph: fix OOB read in decode_watchers() via missing bounds check\n\nceph_start_decoding() validates that struct_len bytes remain in the\nbuffer after the encoding header, but accepts struct_len=0 as valid:\nceph_decode_need(p, end, 0, bad) always passes. When a malicious or\ncompromised OSD sends an obj_list_watch_response_t reply with\nstruct_len=0, ceph_start_decoding() returns success with p == end,\nleaving zero bytes guaranteed for subsequent reads.\n\nThe immediately following ceph_decode_32(p) in decode_watchers() has\nno preceding bounds check. With p == end this is a 4-byte read past\nthe validated buffer boundary. The garbage value is then passed\ndirectly to kzalloc_objs() as the watcher count.\n\nThe sibling function decode_watcher() already uses the safe variants\n(ceph_decode_copy_safe, ceph_decode_64_safe, ceph_decode_skip_32)\nafter its own ceph_start_decoding() call. decode_watchers() is the\nonly site that uses the bare variant, confirming an oversight.\n\nFix by replacing ceph_decode_32(p) with ceph_decode_32_safe(p, end,\n*num_watchers, bad), consistent with the established pattern.\n\nAttacker model: a malicious or compromised OSD in a multi-tenant Ceph\ndeployment (e.g. cloud) can trigger this against any kernel client\nthat calls CEPH_OSD_OP_LIST_WATCHERS, without any further privileges\nbeyond OSD session establishment.\n\n[ idryomov: trim changelog ]", "title": "Vulnerability

If a concurrent NETDEV_UNREGISTER has already\nunlisted the device from the ifindex table, that lookup fails and\ncan_rx_unregister() is silently skipped, leaving a stale CAN filter\npointing at the

resolved:\n\nmm/huge_memory: fix huge_zero_pfn race\n\nPatch series \"mm/huge_memory: fix huge_zero_pfn race\", v2.\n\nThere is a subtle race in the reference-counted huge_zero_folio\nimplementation.\n\nThe fast path atomic logic fails to account for the fact that the shrinker\n(which drops the final huge_zero_refcount pin) can overwrite huge_zero_pfn\nwith the ~0UL sentinel value in shrink_huge_zero_folio_scan() after a\nracing get_huge_zero_folio() installed a valid value there.\n\nThis results in huge_zero_folio being correctly set but huge_zero_pfn\nbeing set incorrectly and thus is_huge_zero_pfn() and consequently\nis_huge_zero_pmd() will misidentify the huge zero folio as being an\nordinary THP folio.\n\nThis can result in the huge zero folio being split and otherwise treated\nincorrectly.\n\nThe solution to this is very subtle as there is an atomic fast path, and\nthus ordering in weakly ordered architectures has to be treated very\ncarefully.\n\nThe first commit fixes the issue by introducing a spinlock around\nhuge_zero_[pfn, folio, refcount] write, with careful consideration paid to\nload/store ordering in the fast path. It is placed first and kept as\nsmall as possible so that it can be backported on its own.\n\nThe second commit is a pure cleanup which reworks the\nCONFIG_PERSISTENT_HUGE_ZERO_FOLIO logic to better separate the persistent\nlogic from the dynamically allocated one.\n\n\nThis patch (of 2):\n\nIf !CONFIG_PERSISTENT_HUGE_ZERO_FOLIO, the huge_zero_folio is refcounted\nby huge_zero_refcount and returned by mm_get_huge_zero_folio().\n\nWhen the caller is done with the huge zero page, its reference count is\ndecremented. Only a shrinker can set the reference count to zero.\n\nA race can unfortunately occur between a shrinker decrementing the\nreference count to zero and a concurrent page fault.\n\nThis is because shrink_huge_zero_folio_scan() might, if very unlucky, be\npreempted between setting huge_zero_refcount to zero and writing an\ninvalid value.\n\nDuring this time get_huge_zero_folio() could write to huge_zero_pfn before\nshrink_huge_zero_folio_scan() resumes.\n\nIn this event the huge zero folio will be persistently misidentified\ncausing the THP code path to be entered inappropriately for the huge zero\nfolio:\n\n CPU 0 CPU 1\n=======================================|=================================\nshrink_huge_zero_folio_scan() |\n atomic_cmpxchg() sets refcount to 0 |\n xchg() sets huge_zero_folio to NULL | get_huge_zero_folio()\n | | atomic_inc_not_zero() -> zero\n preempted for a long time | Allocate new huge zero folio\n | | Write valid huge_zero_folio\n v | Write valid huge_zero_pfn\n Overwrite huge_zero_pfn with ~0UL <--- Invalid overwrite!\n\nThis results in is_huge_zero_pfn() and is_huge_zero_pmd() incorrectly\nreturning false for a huge zero page which could result in issues like the\nhuge zero folio being incorrectly split.\n\nNote that the issue is with huge_zero_pfn not huge_zero_folio, as\nget_huge_zero_folio() uses cmpxchg() gated on huge_zero_folio being NULL\nwith a retry loop and shrink_huge_zero_folio_scan() uses xchg() to set\nhuge_zero_folio.\n\nFix the issue by introducing a spinlock, huge_zero_lock, to prevent\nconcurrent write of huge_zero_folio, huge_zero_pfn and huge_zero_refcount.\n\nThere needs to be significant care taken here to ensure correctness:\n\nThe fast path in get_huge_zero_folio() uses atomic_inc_not_zero(), which\nis outside of the critical section, and means huge zero allocation is\ngated on zero huge_zero_refcount.\n\nThe fast path doesn't use huge_zero_lock, so the critical section is\nirrelevant to it.\n\nSo invariants are required - huge_zero_refcount MUST:\n\n* Only be set in the huge_zero_lock critical section to ensure\n serialisation of huge_zero_pfn, huge_zero_folio and\n---truncated---",

The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still\npresent in v7.1.1.\n\nAn x86_64 allyesconfig build showed no new warnings.

killing the already submitted\nrcv_urb. This leaves the rcv_urb active.\n\nWhen this happens during initialization (e.g., in cxacru_atm_start()), the\ndriver may ignore the error and proceed to call cxacru_poll_status(), which\ninvokes cxacru_cm() again. Attempting to submit the still-active rcv_urb\ntriggers a warning in usb_submit_urb():\n\ncxacru 1-1:1.0: send of cm 0x84 failed (-104)\nATM dev 0: cxacru_atm_start: CHIP_ADSL_LINE_START returned -104\n------------[ cut here ]------------\nURB ffff88812658d200 submitted while active\nWARNING: drivers/usb/core/urb.c:379 at usb_submit_urb+0x79/0x18b0\ndrivers/usb/core/urb.c:379\n...\nCall Trace:\n \n cxacru_cm+0x21a/0xf10 drivers/usb/atm/cxacru.c:631\n cxacru_cm_get_array drivers/usb/atm/cxacru.c:722 [inline]\n cxacru_poll_status+0x178/0x1110 drivers/usb/atm/cxacru.c:828\n cxacru_atm_start+0x185/0x360 drivers/usb/atm/cxacru.c:814\n usbatm_atm_init+0x144/0x3a0 drivers/usb/atm/usbatm.c:927\n usbatm_usb_probe+0x15cb/0x1db0 drivers/usb/atm/usbatm.c:1178\n cxacru_usb_probe+0x17f/0x220 drivers/usb/atm/cxacru.c:1370\n...\n\nTo fix this, ensure that rcv_urb is properly killed if cxacru_cm() aborts\nearly.

resolved:\n\nnet: atlantic: free stranded TX buffers on ring deinit\n\naq_vec_deinit() drains the TX rings with a single aq_ring_tx_clean()\ncall, which frees at most AQ_CFG_TX_CLEAN_BUDGET (256) descriptors and\nstops at hw_head, which no longer moves once aq_vec_stop() has stopped\nthe hardware and NAPI. Completed descriptors beyond the budget and\neverything still posted in [hw_head, sw_tail) keep their skb or\nxdp_frame when the interface goes down: aq_vec_ring_free() then frees\nthe buffer ring and the references are lost for good.\n\nToday this is a silent memory leak on every interface down under\nTX/XDP_TX load. With the conversion of the RX path to page_pool posted\nfor net-next it becomes much more visible: XDP_TX frames carry fragment\nreferences on the RX ring's page_pool, so a single stranded frame keeps\nthe pool's inflight count above zero forever. page_pool_destroy() then\nnever completes, the pool is leaked together with its pages, and\n\"page_pool_release_retry() stalled pool shutdown\" is warned every 60\nseconds from that point on, on every ifdown, XDP detach or ring resize\nunder XDP_TX load.\n\nBring back aq_ring_tx_deinit() as it was before the removal and use it\nfor teardown again, with one extension: TX rings can hold xdp_frames\nnowadays, so release those too.

occur in\ndecode_new_up_state_weight(). This happens because the bounds check for\nthe new_state part is based on calculating its length depending on a len\nvalue read from the incoming message. This calculation may overflow\nleading to an incorrect bounds check. Subsequently, out-of-bounds reads\nmay occur when decoding this part.\n\nThis patch switches the multiplication to use check_mul_overflow() to\nabort processing the osdmap if an overflow occurred. Therefore,\nosdmaps/messages containing large values for len that result in a\nmultiplication overflow are treated as invalid.\n\n[ idryomov: rename new_state_len -> new_state_item_size, formatting

resolved:\n\nmm/huge_memory: unlock i_mmap_rwsem before releasing after-split folios\n\n__folio_split() keeps dereferencing the mapping after the split:\nshmem_uncharge(mapping->host) and remap_page() while the folios are still\nfrozen/locked, and i_mmap_unlock_read(mapping) at the very end, after the\nafter-split folios have been unlocked and freed.\n\nNothing holds an inode reference across that. The split relies on @folio\n-- which the beyond-EOF drop loop never removes, as it starts at\nfolio_next(folio) -- staying locked and in the page cache to hold off\neviction. But the unlock loop unlocks @folio before i_mmap_unlock_read()\nruns. If the caller's @lock_at is a tail beyond EOF, as memory_failure()\npasses when splitting a poisoned tail of a shmem THP that reaches past\ni_size during truncation, it too is gone from the page cache; so once\n@folio is unlocked no locked, in-cache folio pins the inode, and a\nconcurrent final iput() can evict and RCU-free it before\ni_mmap_unlock_read() touches i_mmap_rwsem:\n\n BUG: KASAN:

every mapping dereference while @folio still pins the inode: drop\ni_mmap_rwsem right after remap_page(), before the loop that unlocks and\nfrees the after-split folios, and clear @mapping so the exit path does not\nunlock it again. shmem_uncharge() and remap_page() already run before\nthat point, so after this nothing past the unlock loop touches the inode\nor the mapping.\n\nThis is now a rule

the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if BPF LSM is uninitialized\n\nWhen CONFIG_BPF_LSM=y is set, BPF inode storage maps\n(BPF_MAP_TYPE_INODE_STORAGE) are compiled into the kernel. However,\nif the BPF LSM is not explicitly enabled at boot time (e.g. omitted\nfrom the \"lsm=\" boot parameter), lsm_prepare() is never executed for\nthe BPF LSM.\n\nConsequently, the BPF inode security blob offset\n(bpf_lsm_blob_sizes.lbs_inode) is never initialized and remains at\nits default compiled size of 8 bytes instead of being updated to a\nvalid offset past the reserved struct rcu_head (typically 16 bytes\nor more).\n\nWhen a privileged user creates and updates a BPF_MAP_TYPE_INODE_STORAGE\nmap, bpf_inode() evaluates inode->i_security + 8. This erroneously\naliases the struct rcu_head.func callback pointer at the beginning\nof the inode->i_security blob. During subsequent map element cleanup\nor inode destruction, writing NULL to owner_storage clears the queued\nRCU callback pointer. When rcu_do_batch() later executes the queued\ncallback, it attempts an instruction fetch at address 0x0, triggering\nan immediate kernel panic.\n\nFix this by introducing a global bpf_lsm_initialized boolean flag\nmarked with __ro_after_init. Set this flag to true inside bpf_lsm_init()\nwhen the LSM framework successfully registers the BPF LSM. Gate map\nallocation in inode_storage_map_alloc() on this flag, returning\n-EOPNOTSUPP if the BPF LSM is in turn uninitialized.\n\nThis fail-fast approach prevents userspace from allocating inode\nstorage maps when the supporting BPF LSM infrastructure is absent,\navoiding zombie map states.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s)

"description", "text": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: qrtr: restrict socket creation to the initial network namespace\n\nQRTR keeps its entire port and node state in module-global variables\nthat are not partitioned per network namespace: qrtr_local_nid is a\nsingle global node id (always 1) and qrtr_ports is a single global\nxarray. qrtr_port_lookup() and qrtr_local_enqueue() operate on that\nglobal state with no network-namespace check, and qrtr_create() places\nno restriction on the namespace a socket is created in.\n\nAs a result an unprivileged process that creates an AF_QIPCRTR socket\nin a separate network namespace, e.g. via\nunshare(CLONE_NEWUSER | CLONE_NEWNET), can send QRTR datagrams -\nincluding control-plane messages such as QRTR_TYPE_NEW_SERVER - to QRTR\nsockets owned by another namespace, and vice versa. The receiving\nsocket sees such a message as coming from node id 1, indistinguishable\nfrom a legitimate local client, breaking the isolation that network\nnamespaces are expected to provide.\n\nQRTR is a transport to global hardware endpoints (the modem and other\nremote processors) and has no per-namespace semantics; its in-kernel\nname service already creates its socket in init_net only.

resolved:\n\nmmc: vub300: fix use-after-free on probe failure\n\nThe vub300 driver lifetime-manages its controller state using\nvub300->kref, with vub300_delete() freeing the mmc host when the last\nreference is dropped. The probe error path after the inactivity timer has\nbeen armed still bypasses that lifetime rule, however, and falls through\nto mmc_free_host() directly if mmc_add_host() fails.\n\nThe race window is between arming the inactivity timer and reaching the\nprobe error unwind after mmc_add_host() fails:\n\n probe thread timer/workqueue\n ------------ ---------------\n kref_init(&vub300->kref) ref = 1\n kref_get(&vub300->kref) ref = 2, timer ref\n add_timer(inactivity_timer) fires after one second\n |\n | race window\n |<---------------------------------------------------->\n |\n mmc_add_host(mmc)\n inactivity timer fires\n vub300_queue_dead_work()\n kref_get() ref = 3\n queue_work(deadwork)\n mmc_add_host() fails\n timer_delete_sync()\n mmc_free_host(mmc)\n frees vub300\n deadwork runs\n use-after-free\n\nThe inactivity timeout is one second, so this would require\nmmc_add_host() to both fail and take more than one second to do so. This\nis unlikely to happen in practice, but the error path is still wrong.\n\ntimer_delete_sync() only waits for the timer callback itself. It does\nnot flush deadwork that the callback may already have queued. As a\nresult, queued deadwork can still hold a kref while the probe error path\ndirectly frees the backing mmc host, including the vub300 storage.\n\nFix this by using the same lifetime mechanism as disconnect. Clear\nvub300->interface so that the timer callback and any queued deadwork\nreturn early and drop their references, then drop the initial probe\nreference and return without falling through to err_free_host.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64", "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.arm64",

resolved:\n\nstaging: rtl8723bs: fix OOB read in WMM_param_handler()\n\nWMM_param_handler() copies a fixed-size WMM parameter element out of a\nreceived information element without checking that the element is long\nenough, causing an out-of-bounds read for a short WMM IE.\n\nThe handler reads sizeof(struct WMM_para_element) (18) bytes at\npIE->data + 6, so it requires pIE->length to be at least 24\n(WLAN_WMM_LEN), but it never validates the length. Two of its three\ncallers reach it after matching only the WMM OUI: OnAssocRsp() in\nrtw_mlme_ext.c matches a 6-byte OUI, and join_cmd_hdl() matches a\n4-byte OUI, before calling the handler. A vendor-specific IE carrying\nthe WMM OUI but a length between 6 and 23, placed in an association\nresponse or in the IE blob handed to join_cmd_hdl(), passes the OUI\ncheck and then makes the memcmp() and memcpy() at pIE->data + 6 read\npast the end of the element. OnAssocRsp() parses a frame received from\nthe AP, so this is reachable from a remote peer.\n\nThe remaining caller in rtw_wlan_util.c already guards the handler with\n\"pIE->length == WLAN_WMM_LEN\". Move the equivalent check into the\nhandler itself so every caller is covered; the sibling IE handlers in\nthe same parsing loop (HT_caps_handler(), HT_info_handler(),\nERP_IE_handler()) likewise bound their accesses by pIE->length.", "title": "Vulnerability description" } ], "product_status": { "fixed": [ "Debian-11:bpftool-0:5.10.269-1+tuxcare.els1.amd64",

resolved:\n\nRDMA/rtrs-srv: Bound RDMA-Write length to chunk size in rdma_write_sg\n\nWhen the server answers an RTRS READ, rdma_write_sg() builds the source\nscatter/gather entry for the IB_WR_RDMA_WRITE that returns data to the\npeer. Its length is taken directly from the wire descriptor:\n\n plist->length = le32_to_cpu(id->rd_msg->desc[0].len);\n\nrd_msg points into the chunk buffer that the remote peer filled via\nRDMA-WRITE-WITH-IMM (rtrs_srv_rdma_done() -> process_io_req() ->\nprocess_read()), so desc[0].len is attacker-controlled and, before this\nchange, was only rejected when zero. The source address is the fixed\nchunk start (dma_addr[msg_id]) and the source lkey is the PD-wide\nlocal_dma_lkey, which is not tied to the chunk's MR mapping, so the verbs\nlayer does not constrain the transfer length to max_chunk_size. msg_id\nand off are bounded against queue_depth and max_chunk_size in\nrtrs_srv_rdma_done(), but desc[0].len is a separate field that was not\nchecked against the chunk size.\n\nA peer that advertises desc[0].len larger than max_chunk_size can make\nthe posted RDMA write read past the chunk's mapped region. The resulting\nbehaviour depends on the IOMMU configuration: with no IOMMU or in\npassthrough mode the read may extend into memory adjacent to the chunk\nand be returned to the peer, which can disclose host memory; with a\ntranslating IOMMU the out-of-range access is expected to fault and abort\nthe connection. In either case the transfer exceeds what the protocol\npermits and is driven by a remote peer.\n\nReject a descriptor length above max_chunk_size, mirroring the existing\noff >= max_chunk_size bound in rtrs_srv_rdma_done(). Legitimate clients\ndo not exceed it: the client sets desc[0].len to its MR length, which is\ncapped at the negotiated max_io_size (max_chunk_size - MAX_HDR_SIZE).", "title": "Vulnerability

resolved:\n\ninet: frags: publish queues before arming timer\n\ninet_frag_create() arms the fragment queue timer before inserting the\nqueue into the fqdir rhashtable. If the namespace fragment timeout is\nzero or negative, the timer can run before the queue is published.\n\nThe timer callback then marks the queue complete, tries to remove a node\nthat is not in the hash table yet, and drops the anticipated hash\nreference. Creation can subsequently publish the completed queue without\nrestoring that reference, leaving a stale hash node after the caller drops\nthe remaining reference.\n\nPublish the queue first and arm the timer while holding the queue lock.\nThis makes timer expiry wait until the queue is visible in the hash table,\nso inet_frag_kill() can remove the node and balance the hash reference.", "title":

resolved:\n\nscsi: libiscsi_tcp: Bound SCSI Response data segment to the connection buffer\n\niscsi_tcp_hdr_dissect() receives the data segment of several PDU types\ninto the fixed-size conn->data buffer, which is allocated for\nISCSI_DEF_MAX_RECV_SEG_LEN (8192) bytes. For the LOGIN_RSP, TEXT_RSP,\nREJECT and ASYNC_EVENT opcodes the dissect path already rejects a PDU\nwhose DataSegmentLength exceeds that buffer.\n\nThe SCSI Command Response (ISCSI_OP_SCSI_CMD_RSP) path also copies its\ndata segment (sense/response data) into conn->data via\niscsi_tcp_data_recv_prep(), but it does so without the same check. The\nonly upstream bound on in.datalen is conn->max_recv_dlength, the\ninitiator's advertised MaxRecvDataSegmentLength, which is commonly\nnegotiated well above 8192 (open-iscsi defaults to 262144). A target\nthat returns a SCSI Response with a DataSegmentLength between 8193 and\nmax_recv_dlength therefore overflows the 8192-byte conn->data buffer.\n\nOnce the same bound applies, ISCSI_OP_SCSI_CMD_RSP is handled exactly\nlike those responses: bound the data segment, receive it into conn->data\nwhen present, and otherwise complete the PDU with no data.

resolved:\n\ngpio: ml-ioh: use raw_spinlock_t for the register lock\n\nioh_irq_type() is registered as the irq_chip .irq_set_type callback and\ntakes chip->spinlock with spin_lock_irqsave(). This callback is reached\nfrom __setup_irq() -> __irq_set_trigger() -> chip->irq_set_type() while\nthe caller holds desc->lock, a raw_spinlock_t, with hardirqs disabled.\nThat context is not sleepable, but on PREEMPT_RT a regular spinlock_t is\nan rtmutex-backed sleeping lock, so acquiring it there is invalid.\nioh_irq_enable() and ioh_irq_disable() take the same lock from the\n.irq_enable/.irq_disable callbacks, which are likewise invoked with\ndesc->lock held.\n\nConvert the register lock to raw_spinlock_t. The same lock also\nserializes the GPIO direction/value callbacks and the suspend/resume\nregister save/restore, and those critical sections only perform short\nsequences of MMIO register accesses (ioread32()/iowrite32()); the\n.irq_set_type callback additionally emits a dev_warn() on an unsupported\ntype. None of these are sleepable operations, so keeping this register\nlock non-sleeping is appropriate for the irqchip callbacks and does not\nchange the GPIO-side locking contract.\n\nThis is the same

hlist_del_rcu()) cannot allocate or\nfail. But its guard is inverted: it skips policies with prefixlen <\nthreshold and preallocates for the rest.\n\nprefixlen < threshold is exactly when policy_hash_bysel() returns NULL and\nthe reinsert takes the allocating xfrm_policy_inexact_insert() path. So the\nloop preallocates for the exact policies (which never allocate) and skips\nthe inexact ones, whose bin/node is then allocated GFP_ATOMIC during\nreinsert. On failure the error path only WARN_ONCE()s and continues,\nleaving a poisoned bydst node; the next rebuild's hlist_del_rcu()\ndereferences LIST_POISON2 and takes a GPF. Reachable under memory pressure,\ndeterministic via failslab.\n\nInvert the guard so preallocation covers exactly the reinserted policies;\nthe reinsert then allocates nothing and cannot

the fixed management-body\noffset:\n\n\tlen -= el_off;\n\nFor both beacon and probe response frames, el_off is 36. If the frame is\nshorter than el_off, subtracting it causes the calculated IE length to\nwrap. The length is eventually passed to cfg80211_find_elem_match() as a\nvery large unsigned value, so the element walk runs beyond the RX skb.\n\nThis path is reached from at76_rx_tasklet() while scanning. If the device\ndelivers a truncated beacon or probe response, the oversized IE length\ncauses an out-of-bounds read during scanning.\n\nSkip the IE lookup if the frame does not reach the variable

In cacheless mode the\nclient refetches inode metadata from the server (the source of truth)\non every operation, so by the time v9fs_remove() returns, the locally\ncached nlink may already reflect the post-unlink value:\n\n 1. Client initiates unlink, server processes it and sets nlink to 0\n 2. Client refetches inode metadata (nlink=0) before unlink returns\n 3. Client's v9fs_remove() completes successfully\n 4. Client calls v9fs_dec_count() which calls drop_nlink() on nlink=0\n\nThis race is easily triggered under heavy unlink workloads, such as\nstress-ng's unlink stressor, producing the following warning:\n\n WARNING: fs/inode.c:417 at drop_nlink+0x4c/0xc8\n Call trace:\n drop_nlink+0x4c/0xc8\n v9fs_remove+0x1e0/0x250 [9p]\n v9fs_vfs_unlink+0x20/0x38 [9p]\n vfs_unlink+0x13c/0x258\n ...\n\nIn cacheless mode the server is authoritative and the inode is on its\nway out, so locally adjusting nlink buys nothing. Skip v9fs_dec_count()\nentirely when neither CACHE_META nor CACHE_LOOSE is set, which both\navoids the warning and removes a class of nlink races (two concurrent\nunlinkers observing nlink > 0 and

resolved:\n\nrhashtable: clear stale iter->p on table restart\n\nrhashtable_walk_start_check() has two restart paths when resuming a walk.\nWhen iter->walker.tbl is valid, it re-validates iter->p against the table\nand sets iter->p = NULL if the object is gone. When iter->walker.tbl is\nNULL (table was freed during resize), it resets slot and skip but forgets\nto clear iter->p.\n\nrhashtable_walk_next() then dereferences the stale iter->p, reading\nfreed memory. This is a use-after-free.\n\nAny caller that does multi-fragment rhashtable walks across\nwalk_stop/walk_start boundaries is affected. Concrete cases include\nnetlink_diag (__netlink_diag_dump in net/netlink/diag.c) and TIPC\n(tipc_nl_sk_walk in net/tipc/socket.c).\n\nCrash stack (netlink_diag):\n BUG: KASAN: slab-use-after-free in

resolved:\n\nmm/hugetlb: fix list corruption in allocate_file_region_entries()\n\nallocate_file_region_entries() tops up resv->region_cache with freshly\nallocated file_region descriptors. The allocation uses GFP_KERNEL, so\nresv->lock is dropped around it: the new entries are gathered on a\nstack-local list head, allocated_regions, and spliced into\nresv->region_cache once the lock is re-acquired.\n\nThe splice used list_splice(), which moves the entries but does not\nre-initialize the source head, so allocated_regions is left pointing at an\nentry that now lives on resv->region_cache. The top-up runs in a while\nloop that re-checks the cache deficit after re-acquiring the lock. For a\nshared mapping the resv_map is shared by every mapper of the hugetlbfs\ninode, so a concurrent region_chg()/region_add()/region_del() on the same\nresv_map can consume cache entries during the unlocked window and force a\nsecond iteration. That iteration calls list_add() on the stale head and\ncorrupts the list; with CONFIG_DEBUG_LIST the __list_add_valid() check\ntrips:\n\n list_add corruption. next->prev should be prev (ffffc900011ff7f8),\n but was ffff88814c281460.

hugetlbfs file was mapped MAP_SHARED by both QEMU and a separate\nSPDK/DPDK vhost-user target, generating concurrent region_* traffic on one\nshared resv_map.\n\nUse list_splice_init() so the source

During the window after an entry has been copied but\nbefore the table swap and backlog replay, the old table is still\npublished for packet-side updates while the replacement-table entry\nalready holds the same ip_set_comment_rcu pointer.\n\nIf xt_SET --add-set ... --exist hits that old entry in this window,\nmtype_add() calls ip_set_init_comment() even though packet-side adds\ncarry no comment payload. That call frees the shared comment through the\nold entry, so the replacement-table entry now holds a stale pointer.\nWhen the queued add is replayed on the new table, mtype_add() calls\nip_set_init_comment() again and strlen() dereferences the stale pointer.\n\nFix this in mtype_add() by skipping ip_set_init_comment() when\next->target marks a packet-side add. Userspace adds still update\ncomments, while packet-side adds can no longer free comment storage\nshared with a resize copy.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

resolved:\n\ndma-buf/udmabuf: skip redundant cpu sync to fix cacheline EEXIST warning\n\nWhen CONFIG_DMA_API_DEBUG_SG is enabled, importing a udmabuf into a DRM\ndriver (e.g. amdgpu for video playback in GNOME Videos / Showtime)\ntriggers a spurious warning:\n\n DMA-API: amdgpu 0000:03:00.0: cacheline tracking EEXIST, \\\n overlapping mappings aren't supported\n WARNING: kernel/dma/debug.c:619 at add_dma_entry+0x473/0x5f0\n\nThe call chain is:\n\n amdgpu_cs_ioctl\n -> amdgpu_ttm_backend_bind\n -> dma_buf_map_attachment\n -> [udmabuf] map_udmabuf -> get_sg_table\n -> dma_map_sgtable(dev, sg, direction, 0) // attrs=0\n -> debug_dma_map_sg -> add_dma_entry -> EEXIST\n\nThis happens because udmabuf builds a per-page scatter-gather list via\nsg_set_folio(). When begin_cpu_udmabuf() has already created an sg\ntable mapped for the misc device, and an importer such as amdgpu maps\nthe same pages for its own device via map_udmabuf(), the DMA debug\ninfrastructure sees two active mappings whose physical addresses share\ncacheline boundaries and warns about the overlap.\n\nThe DMA_ATTR_SKIP_CPU_SYNC flag suppresses this check in\nadd_dma_entry() because it signals that no CPU cache maintenance is\nperformed at map/unmap time, making the cacheline overlap harmless.\n\nAll other major dma-buf exporters already pass this flag:\n - drm_gem_map_dma_buf() passes DMA_ATTR_SKIP_CPU_SYNC\n - amdgpu_dma_buf_map() passes DMA_ATTR_SKIP_CPU_SYNC\n\nThe CPU sync at map/unmap time is also redundant for udmabuf:\nbegin_cpu_udmabuf() and end_cpu_udmabuf() already perform explicit\ncache synchronization via dma_sync_sgtable_for_cpu/device() when CPU\naccess is requested through the dma-buf interface.\n\nPass DMA_ATTR_SKIP_CPU_SYNC to dma_map_sgtable() and\ndma_unmap_sgtable() in udmabuf to suppress the spurious warning and\nskip the redundant sync.", "title": "Vulnerability description"

resolved:\n\nInput: evdev - fix information leak in evdev_pass_values()\n\nIn evdev_pass_values(), the input_event structure is allocated on the\nkernel stack and populated field-by-field. However, it is never fully\ninitialized. On architectures where struct input_event contains explicit\nor implicit padding (such as the 32-bit __pad field on SPARC64), these\npadding bytes are left uninitialized.\n\nWhen this event structure is subsequently passed to the client buffer\nand later copied to userspace, the uninitialized padding bytes leak\nkernel stack memory, potentially exposing sensitive information.\n\nSimilar issues exist in __evdev_queue_syn_dropped and __pass_event.\n\nFix this by explicitly zeroing the entire event structure with memset()\nbefore populating its fields. This ensures all padding bytes are cleared\nbefore the data crosses the security boundary.", "title": "Vulnerability description" } ], "product_status": { "fixed": [

checks.\"). These\nare only allowed in subprograms when the latter are BTF annotated and\nhave scalar return types.\n\nThe code generator in bpf_gen_ld_abs() has an abnormal exit path (r0=0 +\nexit) from legacy cBPF times. While the enforcement is on scalar return\ntypes, the verifier must also simulate the path of abnormal exit if the\npacket data load via ld_{abs,ind} failed.\n\nThis is currently not the case. Fix it by having the verifier simulate\nboth success and failure paths, and extend it in similar ways as we do\nfor tail calls. The success path (r0=unknown, continue to next insn) is\npushed onto stack for later validation and the r0=0 and return to the\ncaller is done on the fall-through side.", "title": "Vulnerability

resolved:\n\nInput: sur40 - fix input device registration ordering\n\nIn sur40_probe(), input_register_device() was previously called early before\nthe V4L2 video device and vb2_queue components were fully initialized. If\nuserspace opened the input device immediately upon registration, sur40_open()\nwould trigger and start the sur40_poll() worker thread. This worker thread\ninvokes sur40_process_video() and accesses the uninitialized vb2_queue\nstructure, leading to a data race and potential system crash.\n\nFurthermore, if V4L2 or video registration failed after input_register_device()\nsucceeded, the error path fell through to calling input_free_device() on a\nsuccessfully registered device instead of input_unregister_device(), corrupting\ninput core state.\n\nMove input_register_device() to the very end of sur40_probe(). This ensures\nthe V4L2 and video queue structures are fully initialized before polling can\nstart, and naturally resolves the error path bug since input_free_device()\nis now only called when input registration has not yet occurred.\n\nTo maintain strict LIFO (Last-In, First-Out) teardown ordering, also move\ninput_unregister_device() to the very beginning of sur40_disconnect(). This\nguarantees that the input polling worker thread is stopped before V4L2\nvideo components or control handlers are unregistered.", "title": "Vulnerability description" } ], "product_status": {

This leads to 2 use-after-free\nissues:\n1. New watchdog devices registered after this point will inherit the\n dangling `default_gov`.\n2.

check bounds only after the fact. When idx == raw->curlen,\nraw->msg[idx+1] reads one byte past the received message data into\nthe following struct fields (curchunk_len, curchunk_idx, curlen).\n\nAffected functions:\n - drm_dp_sideband_parse_enum_path_resources_ack()\n full_payload_bw_number and avail_payload_bw_number fields\n - drm_dp_sideband_parse_allocate_payload_ack()\n allocated_pbn field\n - drm_dp_sideband_parse_query_payload_ack()\n allocated_pbn field\n\nFix by using a single combined check (idx + 2 > curlen) before each\n2-byte read.

channel\nprogram, and rejects anything larger than CCWCHAIN_LEN_MAX (256) CCWs.\n\nThe loop itself is \"do..while (count < 257)\", and while the logic in\nis_cpa_within_range() correctly adjusts between the 0-index array of\nCCWs and the count of CCWs starting at 1, this means it would look\nat a possible 257th CCW before ending the loop and (correctly)\nreturning an error.\n\nFix this by
