CVE-2014-3631
Published: 28 September 2014
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.
From the Ubuntu Security Team
A flaw was discovered in the Linux kernel's associative-array garbage collection implementation. A local user could exploit this flaw to cause a denial of service (system crash) or possibly have other unspecified impact by using keyctl operations.
