CVE-2026-93208

The Linux kernel contains a race condition in KASAN involving cache shrinking and CPU hotplug . Specifically, kmem_cache_shrink() fails to hold the cpus_read_lock(), allowing a race where objects are moved to a CPU's shrink_qlist just before that CPU goes offline. Because the offline CPU's list i...
