CVE-2026-18273 (GCVE-0-2026-18273)

Vulnerability from nvd – Published: 2026-08-20 16:14 – Updated: 2026-08-21 20:08

Title

Kenwood DNR1007XR USB Incorrect Default Permissions Local Privilege Escalation Vulnerability

Summary

Kenwood DNR1007XR USB Incorrect Default Permissions Local Privilege Escalation Vulnerability. This vulnerability allows physically present 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 configuration of the mount point for the USB filesystem. The issue results from incorrect permissions on a directory used by the product. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-29070.

Severity

6.6 (Medium)

Title

Kenwood DNR1007XR udhcpd Incorrect Permission Assignment Local Privilege Escalation Vulnerability

Summary

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.

Kenwood DNR1007XR tchdr_bytestream_read Out-Of-Bounds Write Code Execution Vulnerability

Summary

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.

Severity

Kenwood DNR1007XR USB Incorrect Default Permissions Local Privilege Escalation Vulnerability

Summary

Kenwood DNR1007XR USB Incorrect Default Permissions Local Privilege Escalation Vulnerability. This vulnerability allows physically present 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 configuration of the mount point for the USB filesystem. The issue results from incorrect permissions on a directory used by the product.

Title

Kenwood DNR1007XR startUpdateProcess Command Injection Vulnerability

Summary

Kenwood DNR1007XR startUpdateProcess Command Injection 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 startUpdateProcess method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute arbitrary code in the context of root. Was ZDI-CAN-28981.

Severity

6.8 (Medium)

Kenwood DNR1007XR udhcpd Incorrect Permission Assignment Local Privilege Escalation Vulnerability

Summary

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.

Kenwood DNR1007XR tchdr_bytestream_read Out-Of-Bounds Write Code Execution Vulnerability

Summary

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.

Severity

6.8 (Medium)

Title

Kenwood DNR1007XR JKGenService Command Injection Local Privilege Escalation Vulnerability

Summary

Kenwood DNR1007XR JKGenService Command Injection 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 JKGenService. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Was ZDI-CAN-29066.

Severity

7 (High)
