     system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages
     (bsc#1069708).
   - 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).
