CVE-2023-52940
CVE-2023-52940 affects the Linux kernel; it concerns the multi-gen LRU code during cgroup migration. The issue arises in lru_gen_migrate_mm(), which assumes lru_gen_add_mm() runs before it, but in a specific cross-CPU sequence (clone, cgroup_fork, cgroup_procs_write, cgroup_post_fork, task_lock, ...
