Proof-of-concept example code shows a vulnerability in the firmware of two wireless chips sold by Broadcom -- the BCM4325 and the BCM4329. The chips are found in recent devices such as the iPhone 4, iPad, iPad 2, HTC Droid Incredible 2, Motorola Droid X2, and some Edge model cards manufactured by Ford. The flaw makes the devices vulnerable to attacks that render the Wi-Fi connection unusable for the duration of the attack.
