MEDIUM 6.5EPSS 3.07%

Does this matter?

Lower severity and a low EPSS score (3.07%). Track it; it rarely justifies an emergency change on its own.

Description

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 TKIP data-confidentiality protocol.
