CVE-2025-8656

Estado: AnalizadaMedia (6.8)—

Kenwood DMX958XR Protection Mechanism Failure Software Downgrade Vulnerability. This vulnerability allows physically present attackers to downgrade software on affected installations of Kenwood DMX958XR devices. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the libSystemLib library. The issue results from the lack of proper validation of version information before performing an update. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-26355.
