CVE-2026-98398

The Linux kernel contains a vulnerability in the lockdep subsystem where stale class_cache entries are not invalidated when a lock class is zapped (e.g., during module unload or key unregistration). This occurs because zap_class() removes the class from the hash table but does not clear pointers ...
