CVE-2026-23810Cross-BSSID GTK Re-encryption and Traffic Injection
Medium 4.3
In plain English
A medium-severity security flaw in HPE Aruba Networking Wireless Operating Systems (AOS-8 & AOS-10) from Hewlett Packard Enterprise (HPE). There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 10% of all known vulnerabilities).
Official description
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.
