CVE-2024-41075

System crash via mismatched cachefiles request completion

Published Jul 29, 2024 · Updated Aug 5, 2026

Improper request validation in Linux 5.19 through 6.10-rc3 allows local users to crash the system via cachefiles on-demand I/O. The copen and cread completion paths accept mismatched request types, unread copen IDs, and cread file descriptors belonging to different objects. Exploitation requires local low-privileged access to an active cachefiles on-demand cache; malformed completions corrupt request state and terminate the host.
