Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.13.8

Description A race condition in the ALSA subsystem allows local users to cause a denial of service or possibly have other impact via crafted /dev/snd/seq ioctl calls, related to sound/core/seq/seq clientmgr.c and sound/core/seq/seq ports.c.

Recommendations For Linux kernel versions prior to 4.13.8, update to version 4.13.8 or later to resolve the issue. As a temporary workaround, consider restricting access to the /dev/snd/seq ioctl calls to minimize the risk of exploitation.
