CVE-2014-3631
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.
| Software | From | Fixed in |
|---|---|---|
| linux / linux_kernel | 3.13 | 3.14.19 |
| linux / linux_kernel | 3.15 | 3.16.3 |
