The vulnerability of the implementations of WPA and WPA2 driver 6.1316.1209 Wi-Fi adapter ALFA allows a intruder to inject and decode packets in WPA or WPA2 networks.

The vulnerability of WPA and WPA2 driver version 6.1316.1209 Wi-Fi adapter implementations lies in the lack of verification of the integrity of fragmented TKIP packets. Exploiting this vulnerability allows a malicious actor to inject and decode packets in WPA or WPA2 networks remotely...

CVE-2020-26141

An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation does not verify the Message Integrity Check authenticity of fragmented TKIP frames. An adversary can abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the...
