CVE-2026-18270

Kenwood DNR1007XR udhcpd Incorrect Permission Assignment Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Kenwood DNR1007XR devices. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the udhcpd service. The issue results from incorrect permissions set on a resource used by the service. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of root. Was ZDI-CAN-29111.

Summary		(es) Vulnerabilidad de Escalada de Privilegios Local por Asignación Incorrecta de Permisos en udhcpd de Kenwood DNR1007XR. Esta vulnerabilidad permite a atacantes locales escalar privilegios en instalaciones afectadas de dispositivos Kenwood DNR1007XR. Un atacante debe primero obtener la capacidad de ejecutar código con bajos privilegios en el sistema objetivo para explotar esta vulnerabilidad. La falla específica existe dentro del servicio udhcpd. El problema resulta de permisos incorrectos establecidos en un recurso utilizado por el servicio. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código en el contexto de root. Fue ZDI-CAN-29111.
