Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 4.8.7

Description The issue is related to the mishandling of unsuccessful crypto registration in conjunction with successful key-type registration. This can be exploited by local users to cause a denial of service, resulting in a NULL pointer dereference and panic, or possibly have other unspecified impacts. The exploitation is possible via a crafted application that uses the big key data type.

Recommendations For Linux kernel versions prior to 4.8.7, update to version 4.8.7 or later to resolve the issue.
