Description D'juan McDonald (domhnall) 2017-08-20 18:00:18 UTC 
From $URL:

Race condition in fs/timerfd.c in the Linux kernel before 4.10.15 allows 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.
