CVE-2012-6537
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.
Does this matter?
Lower severity and a low EPSS score (0.36%). Track it; it rarely justifies an emergency change on its own.
