  "details" : [ "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.", "A race condition was found in the Linux kernel before version 4.11-rc1 in 'fs/timerfd.c' file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper 'might_cancel' queuing.  An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely." ],
  "statement" : "This issue does not affect Red Hat Enterprise Linux 5 as the code with the flaw is not present in the products listed.\nThis issue affects Red Hat Enterprise Linux 6 and 7. Future updates for the respective releases may address this issue.\nThis issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux MRG-2. This flaw is not currently planned to be addressed in future updates due to MRG-2 being an EUS release.
