Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel up to 6.6.86/6.12.22/6.13.10/6.14.1. Affected is the function check_unsafe_exec of the file fs/exec.c. The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: exec: fix the racy usage of fs_struct->in_exec check_unsafe_exec() sets fs->in_exec under cred_guard_mutex, then execve() paths clear fs->in_exec lockless. This is fine if exec succeeds, but if it fails we have the following race: T1 sets fs->in_exec = 1, fails, drops cred_guard_mutex T2 sets fs->in_exec = 1 T1 clears fs->in_exec T2 continues with fs->in_exec == 0 Change fs/exec.c to clear fs->in_exec with cred_guard_mutex held.

The advisory is available at git.kernel.org. This vulnerability is traded as CVE-2025-22029 since 12/29/2024. The exploitability is told to be difficult. Technical details are known, but there is no available exploit.
