CWEhttps://cwe.mitre.org/data/definitions/476.html

The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.

Weakness

The product dereferences a pointer that it expects to be valid but is NULL.
