If you have a Centrino based Laptop, I suggest you go check the following. There are no reported vulnerabilities yet, but now this is out in the open, you can bet there will be some coming along in the very near future. Also, I doubt if this will be issued via a Windows Update, so you will probably have to go to Intels site and download the update
Security vulnerabilities exist in the Microsoft* Windows* drivers for the Intel® 2200BG and 2915ABG PRO/Wireless Network Connection Hardware because of the way that they currently handle certain frames. An attacker could potentially exploit these vulnerabilities which could potentially lead to remote code execution and system control.
