CVE-2011-2518

Published: 01 July 2011

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.

From the Ubuntu security team

A flaw was discovered in the TOMOYO LSM's handling of mount system calls. An unprivileged user could oops the system causing a denial of service.
