CVE-2025-34251 – Tesla Telematics Control Unit (TCU) < v2025.14 Authentication Bypass

CVE ID : CVE-2025-34251

Published : Oct. 7, 2025, 12:15 a.m. | 18 minutes ago

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.

Severity: 8.6 | HIGH
