CVE-2026-42577 affects Netty 4.2.x only (advisory range >= 4.2.0.Final, < 4.2.13.Final). An fd left registered with an epoll event mask of 0 is woken forever by the unmaskable EPOLLERR/EPOLLHUP after a RST on a half-closed connection. Target 4.1.122.Final is NOT affected due to architectural differences. The patch modifies EpollIoHandler.java and EpollIoOps.java, part of 4.2's IoHandler/IoOps abstraction. Neither file exists in 4.1.x, which registers via EpollEventLoop.modify() off AbstractEpollChannel.flags. That field is seeded Native.EPOLLET, and no read/close/half-close path clears it (only the explicit pre-registration setEpollMode(LEVEL_TRIGGERED) opt-in), so the registration stays edge-triggered and the RST is reported once per edge instead of on every epoll_wait. The chain from INPUT (connection state change) to GOAL (CPU busy-loop via empty event mask) is broken at step (ii): the target cannot produce an empty event mask. Verdict: not_affected. Justification: code_not_reachable (Rule 5 Type A2).",
