Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 2.6.39.2

Description The issue is related to the tomoyo mount acl function in the Linux kernel, which calls the kern path function with arguments taken directly from a mount system call. This allows local users to cause a denial of service (OOPS) or possibly have unspecified other impact via a NULL value for the device name.

Recommendations For Linux kernel versions prior to 2.6.39.2, update to version 2.6.39.2 or later to resolve the issue.
