CVE-2020-26143 is a Wi-Fi implementation flaw in which a device operating on a protected wireless network incorrectly accepts fragmented plaintext data frames. In the provided context, the ALFA Windows 10 driver 1030.36.604 for the AWUS036ACH adapter is specifically affected, and the issue is also described more broadly as impacting IEEE 802.11 implementations. The flaw affects protected WEP, WPA, WPA2, and WPA3 networks because the implementation improperly processes fragmented frames that should not be accepted as plaintext once link-layer protection is in use. An attacker within radio range can abuse this behavior to inject arbitrary data frames into the protected network independent of the configured Wi-Fi security mode.
