CVE-2026-23809MAC Address Spoofing leads to Inter-BSSID Isolation Bypass Resulting in Traffic Redirection
Medium 5.4
In plain English
A medium-severity uncontrolled resource consumption in HPE Aruba Networking Wireless Operating System (AOS-10 & AOS-8) 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 0.3% (higher than 21% of all known vulnerabilities).
Official description
A technique has been identified that adapts a known port-stealing method to Wi-Fi environments that use multiple BSSIDs. By leveraging the relationship between BSSIDs and their associated virtual ports, an attacker could potentially bypass inter-BSSID isolation controls. Successful exploitation may enable an attacker to redirect and intercept the victim's network traffic, potentially resulting in eavesdropping, session hijacking, or denial of service.
