Last modified

CVE-2012-6536 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.37% chance of exploitation in the next 30 days.
