Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.13

Description: The issue might allow local users to cause a denial of service. This is related to the kill something info function in kernel/signal.c, which can be affected when an unspecified architecture and compiler is used, potentially via an INT MIN argument.

Recommendations: For versions prior to 4.13, update to version 4.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the kill something info function until a patch is available.
