Summary
The vulnerability in the tchdr_bytestream_read function of Kenwood DNR1007XR causes an out-of-bounds write. An attacker with physical access, without authentication, can exploit the lack of data validation to execute arbitrary code as root.
Risk Assessment
The risk is the potential for arbitrary code execution by an attacker with physical access, potentially leading to device compromise and security breach.
Recommendation
It is recommended to restrict physical access to the device and apply vendor patches if available.

Original NVD description (English source)
Kenwood DNR1007XR tchdr_bytestream_read Out-Of-Bounds Write Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Kenwood DNR1007XR devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the tchdr_bytestream_read function. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-28980.
