CVE-2026-18269

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.

Summary		(es) Vulnerabilidad de ejecución de código por escritura fuera de límites en tchdr_bytestream_read de Kenwood DNR1007XR. Esta vulnerabilidad permite a atacantes presentes físicamente ejecutar código arbitrario en instalaciones afectadas de dispositivos Kenwood DNR1007XR. La autenticación no es requerida para explotar esta vulnerabilidad. La falla específica existe dentro de la función tchdr_bytestream_read. El problema resulta de la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede resultar en una escritura más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de root. Fue ZDI-CAN-28980.
