CVE-2026-64418

CVE-2026-64418 is a Linux kernel memory-management race in the shrinker subsystem. The vulnerability arises when the shrinker_info array is freed while still accessible, causing use-after-free or double-free. The root cause is that alloc_shrinker_info() can drop shrinker_mutex before finishing in...
