Re-exported NFSv3 has been seen to Oops if the fl_file field\nis NULL.", "A flaw was found in the Linux kernel's `lockd` component, which handles file locking. A local user could exploit this vulnerability by interacting with re-exported NFSv3 (Network File System version 3) shares. This could cause the kernel to crash, leading to a Denial of Service (DoS) for the system." ],
