Description Prasad J Pandit 2013-07-03 14:54:24 EDT
Linux kernel built with the IPSec key_socket support(CONFIG_NET_KEY=m) is
vulnerable to an information leakage flaw. It occurs while using key_socket's
notify interface.

A user/program able to access the PF_KEY key_sockets could use this flaw to
leak kernel memory bytes.
