CVE-2024-50010

Kernel warning via racy noexec flag check

Published Oct 21, 2024 · Updated May 12, 2026

Race condition in fs/exec.c in Linux 5.9 and later allows local users to trigger an unwarranted kernel warning during execve. A redundant path_noexec check reads mount noexec state after the permission check, so a concurrent flag change can make WARN_ON report a condition that execution did not violate. Exploitation requires local low-privileged access and a race with changing noexec state; published evidence identifies no confidentiality or integrity impact.
