The keyctl_session_to_parent function in security/keys/keyctl.c in the
Linux kernel 2.6.35.4 and earlier expects that a certain parent session
keyring exists, which allows local users to cause a denial of service (NULL
pointer dereference and system crash) or possibly have unspecified other
impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.
