CVE-2025-8653 Details
Description
Kenwood DMX958XR JKRadioService Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Kenwood DMX958XR. Authentication is not required to exploit this vulnerability. The specific flaw exists within the JKRadioService. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26312.
A stack-based buffer overflow vulnerability allowing remote code execution has been identified in the Kenwood DMX958XR radio model, specifically within the JKRadioService component. This issue arises from inadequate validation of user-supplied data length before it is copied to a fixed-length stack-based buffer. As a result, network-adjacent attackers can exploit this vulnerability to execute arbitrary code with root privileges on the affected device. Notably, no authentication is required to exploit this vulnerability.
Due to the nature of this vulnerability, the primary recommended mitigation strategy is to limit interaction with the affected product.
