Description Prasad J Pandit 2014-03-10 06:24:56 EDT
Linux kernel built with the IPv6 protocol support(CONFIG_IPv6) is vulnerable
to a kernel crash caused by a flood of IPv6 router advertisement(RA) packets.
It occurs while processing the IPv6 router advertisement packets.

A remote attacker in the same layer 2 segment can use this flaw to crash the
kernel on a target system, resulting in DoS.
