Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.9.13

Description The issue is related to insufficient input validation in the LLC subsystem of the Linux kernel. This can be exploited to cause a denial of service. Local users can potentially cause a denial of service or have other unspecified impacts by making crafted system calls.

Recommendations For Linux kernel versions prior to 4.9.13, update to version 4.9.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the LLC subsystem to minimize the risk of exploitation.
