CVE-2011-2518 is a vulnerability of currently unknown severity. The tomoyo_mount_acl function in security/tomoyo/mount.c in the Linux kernel before 2.6.39.2 calls the kern_path function with arguments taken directly from a mount system call, which allows local users to cause a denial of service (OOPS) or possibly have unspecified other impact via a NULL value for the device name.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
