Denial of Service Vulnerability in Linux Kernel's assoc_array_gc Function

CVE-2014-3631 · HIGH Severity

AV:L/AC:L/AU:N/C:C/I:C/A:C

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.
