CVE-2024-53218

Kernel crash via concurrent F2FS shutdown race

Published Dec 27, 2024 · Updated May 11, 2026

Use-after-free in F2FS in The Linux Kernel Organization Linux allows local users with CAP_SYS_ADMIN to crash the kernel via concurrent shutdowns. Concurrent f2fs_stop_gc_thread() calls can free the shared gc_thread object on one CPU while another CPU dereferences its f2fs_gc_task pointer. Triggering the race requires CAP_SYS_ADMIN and concurrent F2FS shutdown paths; the demonstrated consequence is a general-protection fault and kernel crash.
