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

Description The issue is related to the use of an incorrect type of mutex in the sound/core/timer.c file, which can be exploited by local users to cause a denial of service. This can be achieved through a crafted ioctl call, resulting in a race condition, use-after-free, and potentially a system crash.

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