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 system crash, via a crafted ioctl call. This is related to the
snd timer close and snd timer stop functions in the sound/core/timer.c file.Recommendations
For Linux kernel versions prior to 4.4.1, update to version 4.4.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the ioctl call related to the
snd timer close and snd timer stop functions to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
