Technical description

net/xfrm/xfrm_user.c in the Linux kernel before 3.6 does not verify that the actual Netlink message length is consistent with a certain header field, which allows local users to obtain sensitive information from kernel heap memory by leveraging the CAP_NET_ADMIN capability and providing a (1) new or (2) updated state.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
