CVE-2017-10661

Published: 19 August 2017

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.

From the Ubuntu security team

Dmitry Vyukov discovered that a race condition existed in the timerfd subsystem of the Linux kernel when handling might_cancel queuing. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
