Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.4.1

Description The issue allows local users to cause a denial of service, resulting in a race condition, use-after-free, and system crash via a crafted ioctl call. This is due to a locking approach in sound/core/timer.c that does not consider slave timer instances.

Recommendations For Linux kernel versions prior to 4.4.1, update to version 4.4.1 or later to resolve the issue.
