Intel Centrino wireless drivers fail to properly process malformed frames

Vulnerability Note VU#524332

Original Release Date: 2007-04-05 | Last Revised: 2007-04-09


Microsoft Windows drivers for Intel Centrino wireless adapters fail to properly handle malformed frames. This vulnerability may allow an attacker to execute arbitrary code.


The Microsoft Windows drivers for Intel Centrino 2200BG and 2915ABG PRO wireless adapters fail to properly handle malformed frames. If an attacker within 802.11 radio range of an affected wireless adapter sends a specially crafted frame to that adapter, they may be able to trigger this vulnerability.

Affected drivers include w22n50.sys, w22n51.sys, w29n50.sys, and w29n51.sys. For more information refer to Intel Security Advisory INTEL-SA-00001.


An unauthenticated, remote attacker may be able to execute arbitrary code with kernel-level privileges.


Upgrade Intel drivers
Intel has released updates to address this issue. The Intel support site also provides a tool to assist users in determining the model and version of the wireless adapter they are using.

Disable the affected wireless adapter

Until updates can be applied, turning off the affected wireless adapter may mitigate this vulnerability.
