When a file has an empty security context, listing it via 'ls(1)' could trigger this crash. Only user/processes with CAP_MAC_ADMIN privileges are allowed to set the SELinux security context of a file. A user/process with CAP_MAC_ADMIN privileges could use this flaw to crash the kernel, resulting in a DoS.
