CVE-2026-23810 — Cross-BSSID GTK Re-encryption and Traffic Injection

Description (CNA)

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.
