Executive Summary

CVE-2025-69515 affects the JXL 9 Inch Car Android Double Din Player running Android 12.0. The vulnerability exists in the GNSS Receiver Module and related location services because the system does not validate the integrity of incoming GPS signals.

An attacker can broadcast spoofed GPS signals using a Software Defined Radio (SDR) device from nearby RF proximity. The infotainment system may accept these falsified signals as legitimate, causing it to report incorrect or static location data.

This attack requires no authentication or user interaction and can be performed remotely without physical access to the device.

Impact Analysis

The vulnerability allows an attacker to manipulate the vehicle's reported location by spoofing GPS signals, which can lead to incorrect navigation information.

This impacts the integrity and availability of the infotainment system's location data, potentially causing navigation errors or misleading location reporting.

However, the attack does not affect data confidentiality and is limited to the infotainment system.

Detection Guidance

This vulnerability involves the JXL 9 Inch Car Android Double Din Player accepting falsified GPS signals due to lack of integrity validation in the GNSS input path. Detection involves monitoring the infotainment system's GPS data for inconsistencies or static location reports that do not correspond to actual movement.

Since the attack requires an attacker to be in RF proximity using a Software Defined Radio (SDR) to broadcast spoofed GPS signals, detection can include checking for unusual GPS signal strength or sudden location jumps.

Specific commands are not provided in the available resources, but general approaches could include:

• Using Android debugging tools (adb) to monitor GPS location data logs for anomalies.
• Running commands to check GPS chipset status or logs, such as `adb shell dumpsys location` to review location service status.
• Monitoring for static or inconsistent GPS coordinates over time.

Mitigation Strategies

Immediate mitigation steps focus on reducing the risk of GPS spoofing attacks on the JXL 9 Inch Car Android Double Din Player infotainment system.

• Physically secure the vehicle and infotainment system to prevent attackers from gaining RF proximity needed to broadcast spoofed GPS signals.
• Avoid parking or operating the vehicle in areas where attackers could easily use SDR devices nearby.
• Monitor GPS data for unusual behavior and report inconsistencies to the device manufacturer for firmware updates or patches.
• Request or apply any available software or firmware updates from the vendor that address GPS signal validation.
