Linux kernel built with the IPSec keysocket support(CONFIGNETKEY=m) is vulnerable to an information leakage flaw. It occurs while using keysocket's notifypolicy interface.
A user/program able to access the PFKEY keysockets could use this flaw to leak kernel memory bytes.

— Red Hat
The keynotifypolicyflush function in net/key/afkey.c in the Linux kernel before 3.9 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notifypolicy interface of an IPSec keysocket.
