kernel: keys: incorrect termination condition in assoc array garbage collection
Published Sep 28, 2014
7.2
HIGHCVSS 2.0
EPSS 0.96%
Description
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.
