Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.5.7

Description The issue is related to the sock setsockopt function in the Linux kernel, which does not properly validate the association of a keepalive action with a stream socket. This allows local users to cause a denial of service, resulting in a system crash, by creating a raw socket.

Recommendations For Linux kernel versions prior to 3.5.7, update to version 3.5.7 or later to resolve the issue.
