CVE-2014-3631 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.96% chance of exploitation in the next 30 days.
