In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: improve CSA/ECSA connection refusal As mentioned in the previous commit, we pretty quickly found that some APs have ECSA elements stuck in their probe response, so using that to not attempt to connect while CSA is...

New Wi-Fi Protocol Security Flaw Affecting Linux, Android and iOS Devices

A group of academics from Northeastern University and KU Leuven has disclosed a fundamental design flaw in the IEEE 802.11 Wi-Fi protocol standard, impacting a wide range of devices running Linux, FreeBSD, Android, and iOS. Successful exploitation of the shortcoming could be abused to hijack TCP...

Polite WiFi loophole could allow attackers to drain device batteries

Researchers at the University of Waterloo in Ontario have further researched a loophole in the WiFi protocol that was dubbed "polite WiFi". Last year the researchers published a study in which they showed someone could use this loophole to triangulate the location of any WiFi enabled device. Now,...
