Vulnerability Title
Tesla Telematics Control Unit (TCU) < v2025.14 Authentication Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
Tesla Telematics Control Unit (TCU) firmware prior to v2025.14 contains an authentication bypass vulnerability. The TCU runs the Android Debug Bridge (adbd) as root and, despite a “lockdown” check that disables adb shell, still permits adb push/pull and adb forward. Because adbd is privileged and the device’s USB port is exposed externally, an attacker with physical access can write an arbitrary file to a writable location and then overwrite the kernel’s uevent_helper or /proc/sys/kernel/hotplug entries via ADB, causing the script to be executed with root privileges.
