Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.6

Description The issue allows local users to obtain sensitive information from kernel heap memory. This can be achieved by leveraging the CAP NET ADMIN capability and providing a new or updated state, due to the lack of verification of the actual Netlink message length against a certain header field in the net/xfrm/xfrm user.c file.

Recommendations For Linux kernel versions prior to 3.6, update to version 3.6 or later to resolve the issue.
