The fib6_add_rt2node function in net/ipv6/ip6_fib.c in the IPv6 stack
in the Linux kernel through 3.10.1 does not properly handle Router
Advertisement (RA) messages in certain circumstances involving three
routes that initially qualified for membership in an ECMP route set
until a change occurred for one of the first two routes, which allows
remote attackers to cause a denial of service (system crash) via a
crafted sequence of messages.
