Kenwood DMX958XR JKRadioService Stack-Based Buffer Overflow Remote Code Execution Vulnerability

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.

Impact

Exploitation of this vulnerability allows for arbitrary code execution on the affected device, with the executed code running in the context of the root user.

Remediation

Due to the nature of this vulnerability, the primary recommended mitigation strategy is to limit interaction with the affected product.
