  "details" : [ "The assoc_array_gc function in the associative-array implementation in lib/assoc_array.c in the Linux kernel before 3.16.3 does not properly implement garbage collection, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via multiple \"keyctl newring\" operations followed by a \"keyctl timeout\" operation.", "A flaw was found in the way the Linux kernel's keys subsystem handled the termination condition in the associative array garbage collection functionality. A local, unprivileged user could use this flaw to crash the system." ],
