CVE-2013-4129

The bridge multicast implementation in the Linux kernel through 3.10.3 does
not check whether a certain timer is armed before modifying the timeout
value of that timer, which allows local users to cause a denial of service
(BUG and system crash) via vectors involving the shutdown of a KVM virtual
machine, related to net/bridge/br_mdb.c and net/bridge/br_multicast.c.
