CVE-2012-6537

Published: 07 March 2013

net/xfrm/xfrm_user.c in the Linux kernel before 3.6 does not initialize certain structures, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability.

From the Ubuntu security team

Mathias Krause discovered several errors in the Linux kernel's xfrm_user implementation. A local attacker could exploit these flaws to examine parts of kernel memory.
