CVE-2020-26140: An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H.

Security readout for executives and security teams

This flaw affects the ALFA AWUS036H Windows 10 driver version 6.1316.1209. In protected Wi-Fi networks, the driver may accept unencrypted data frames that should be rejected, allowing arbitrary data-frame injection. The public bundle does not provide a CVSS score, confirmed ALFA fix, or active exploitation evidence. Exposure is most likely where Windows 10 systems use ALFA AWUS036H adapters with driver 6.1316.1209. Related advisories cover other vendors, but this CVE record specifically names the ALFA driver; do not assume broader product impact without matching vendor guidance. Treat this as a targeted Wi-Fi exposure issue rather than an internet-scale emergency. Prioritize environments using the named ALFA adapter, especially on privileged or sensitive networks. The absence of CVSS, KEV listing, and ALFA fix details lowers confidence, not the need to inventory. Mitigation focus: Inventory Windows 10 hosts using ALFA AWUS036H adapters and driver 6.1316.1209.; Check ALFA or operating-system driver guidance for an updated or corrected driver.; Remove, replace, or disable affected adapters where no trusted fix is available..
