CVE-2024-45000

A race condition vulnerability was found in the Linux kernel. A race condition in the fscache_cookie subsystem leads to a NULL pointer dereference. The issue occurred when multiple processes accessed a cached file while it was being withdrawn, causing the cache's metadata to clear prematurely.

This issue is classified as Moderate severity rather than Important because, while it leads to a NULL pointer dereference and a subsequent kernel crash, it requires specific conditions to trigger. The vulnerability depends on a race condition between multiple processes accessing the same cached file, which is not easily exploitable in most environments. Additionally, it does not directly enable privilege escalation, remote code execution, or data corruption.
