"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: safely discard unregistered deferred locks\n\nWhen vfs_lock_file() defers a lock, smb2_lock() puts its ksmbd_lock on\nrollback_list before allocating and registering the asynchronous work.\nIf either operation fails, rollback assumes that smb_lock->conn is\ninitialized and dereferences NULL. The deferred file_lock also remains\nlinked into the VFS blocked-lock state while it is freed.\n\nKeep the lock off rollback_list until async setup succeeds. On setup\nfailures, explicitly unblock and wake the deferred lock before freeing it\nand its ksmbd wrapper."
