CVE-2013-1826 Information

Description

The xfrm_state_netlink function in net/xfrm/xfrm_user.c in the Linux kernel before 3.5.7 does not properly handle error conditions in dump_one_state function calls which allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) by leveraging the CAP_NET_ADMIN capability.
