CVE-2025-5476

Sony XAV-AX8500 Bluetooth Improper Isolation Authentication Bypass Vulnerability. This vulnerability allows network-adjacent attackers to bypass authentication on affected Sony XAV-AX8500 devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of ACL-U links. The issue results from the lack of L2CAP channel isolation. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-26284.
