[CLSA-2026:1793264434] Fix CVE(s): CVE-2026-97205
Type:
security
Severity:
Critical
Release date:
2026-10-29 09:00:46 UTC
Description:
* SECURITY UPDATE: use-after-free via an unbounded number of pending asynchronous operations on a request - debian/patches/CVE-2026-97205.patch: add NGX_HTTP_MAX_BLOCKED and check r->main->blocked against it in the copy filter, the cache lock, the cache aio read and the upstream thread handler, so the 8-bit pending operation counter can no longer wrap to zero and let the request pool be freed while operations still reference it; operations beyond the limit are performed synchronously or refused - CVE-2026-97205
