 denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt
 system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages

- CVE-2017-10661: Race condition in fs/timerfd.c allowed local users to
 gain privileges or cause a denial of service (list corruption or
 use-after-free) via simultaneous file-descriptor operations that
 leverage improper might_cancel queueing (bsc#1053153).");
