Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.10.3

Description The issue is related to the bridge multicast implementation in the Linux kernel, which does not properly check if a certain timer is armed before modifying its timeout value. This can be exploited by local users to cause a denial of service, resulting in a system crash, particularly when shutting down a KVM virtual machine. The problem is associated with the net/bridge/br mdb.c and net/bridge/br multicast.c files.

Recommendations For Linux kernel versions prior to 3.10.3, update to version 3.10.3 or later to resolve the issue.
