CVE-2011-0716

Publication date 12 January 2012

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The br_multicast_add_group function in net/bridge/br_multicast.c in the Linux kernel before 2.6.38, when a certain Ethernet bridge configuration is used, allows local users to cause a denial of service (memory corruption and system crash) by sending IGMP packets to a local interface.

From the Ubuntu Security Team

A flaw was found in the Linux Ethernet bridge's handling of IGMP (Internet Group Management Protocol) packets. An unprivileged local user could exploit this flaw to crash the system.
