Vulnerability Name:

CVE-2014-3631 (CCN-96186)

Assigned:2014-09-09
Published:2014-09-09
Updated:2023-02-13
Summary: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.
