Hi,

found in the mainline kernel git:

commit a5cc68f3d63306d0d288f31edfc2ae6ef8ecd887
Author: Mathias Krause <minipli () googlemail com>
Date:   Wed Jun 26 23:52:30 2013 +0200

    af_key: fix info leaks in notify messages

    key_notify_sa_flush() and key_notify_policy_flush() miss to initialize
    the sadb_msg_reserved member of the broadcasted message and thereby
    leak 2 bytes of heap memory to listeners. Fix that.
