Vulnerability from github – Published: 2026-03-04 18:31 – Updated: 2026-03-04 18:31

Details

A vulnerability in the packet processing logic may allow an authenticated attacker to craft and transmit a malicious Wi-Fi frame that causes an Access Point (AP) to classify the frame as group-addressed traffic and re-encrypt it using the Group Temporal Key (GTK) associated with the victim's BSSID. Successful exploitation may enable GTK-independent traffic injection and, when combined with a port-stealing technique, allows an attacker to redirect intercepted traffic to facilitate machine-in-the-middle (MitM) attacks across BSSID boundaries.

Severity

4.3 (Medium)
