Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.16.3

Description The issue is related to the associative-array implementation in the Linux kernel, specifically the assoc array gc function, which does not properly implement garbage collection. This allows local users to cause a denial of service, resulting in a NULL pointer dereference and system crash, or possibly have unspecified other impact. The exploitation involves multiple "keyctl newring" operations followed by a "keyctl timeout" operation.

Recommendations For Linux kernel versions prior to 3.16.3, update to version 3.16.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the keyctl command to minimize the risk of exploitation.
