CVE-2024-26625Public exploit

Kernel memory corruption via stale LLC wait queue

Published Mar 6, 2024 · Updated Aug 5, 2026

A use-after-free in the LLC socket release path in Linux before 6.8 allows local users with CAP_NET_RAW to crash or corrupt the kernel. The release path omits sock_orphan(), leaving sk_wq pointing into a freed socket inode when queued data completes transmission. Exploitation requires local AF_LLC system calls and CAP_NET_RAW; successful triggering permits kernel memory access, control-flow corruption, or a system panic.
