CVE-2013-6431

Published: 09 December 2013

The fib6_add function in net/ipv6/ip6_fib.c in the Linux kernel before 3.11.5 does not properly implement error-code encoding, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability for an IPv6 SIOCADDRT ioctl call.

From the Ubuntu security team

A flaw was discovered in the Linux kernel's fib6 error-code encoding for IPv6. A local user with the CAT_NET_ADMIN capability could exploit this flaw to cause a denial of service (system crash).
