CVE-2024-41058

Kernel memory read via volume withdrawal race

Published Jul 29, 2024 · Updated May 11, 2026

A use-after-free in Linux kernel CacheFiles allows attackers to trigger an invalid kernel-memory read during volume withdrawal. Concurrent failed EROFS mount cleanup can free an fscache_volume while daemon exit still traverses the cache list and reads its n_accesses field. Reaching the flaw requires the documented local withdrawal race; published testing demonstrates a KASAN-detected slab read but does not establish code execution or data disclosure.
