** Description changed:
- A slave timer instance might be still accessible in a racy way while
- operating the master instance as it lacks of locking. Since the master
- operation is mostly protected with timer->lock, we should cope with it
- while changing the slave instance, too.
+ sound/core/timer.c in the Linux kernel before 4.4.1 employs a locking
+ approach that does not consider slave timer instances, which allows
+ local users to cause a denial of service (race condition, use-after-
+ free, and system crash) via a crafted ioctl call.
