An adversary can abuse this to inject arbitrary data frames independent of the network configuration.

MEDIUM 6.5EPSS 4.17%

Does this matter?

Lower severity and a low EPSS score (4.17%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can abuse this to inject arbitrary data frames independent of the network configuration.
