The (1) key_notify_sa_flush and (2) key_notify_policy_flush functions in net/key/af_key.c in the Linux kernel before 3.10 do not initialize certain structure members, which allows local users to obtain sensitive information from kernel heap memory by reading a broadcast message from the notify interface of an IPSec key_socket.
