The Microsoft Windows drivers for Intel Centrino 2200BG and 2915ABG PRO wireless adapters fail to properly handle malformed frames. If a remote attacker within transmitting 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-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.

Public reports indicate there may be compatibility issues when installing the new drivers. Known issues with the new drivers are documented in the driver release notes. Users should consult the release notes specific to their driver before applying updates.

Users are encouraged to consult their OEM and hardware providers to determine the best way to update drivers. From Intel:
