CVE-2023-52468

The CVE-2023-52468 entry describes a Linux kernel use-after-free in class_register. The issue arises because lock_class_key remains registered in lock_keys_hash after subsys_private is freed in an error path, so a task iterating the hash later may trigger a use-after-free. The fix unregisters the...
