Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.11.5

Description The issue is related to the fib6 add function in the Linux kernel, which does not properly implement error-code encoding. This allows local users with the CAP NET ADMIN capability to cause a denial of service, resulting in a NULL pointer dereference and system crash, by making an IPv6 SIOCADDRT ioctl call.

Recommendations For Linux kernel versions prior to 3.11.5, update to version 3.11.5 or later to resolve the issue.
