Physical root code execution via unlocked ADB
Published Oct 6, 2025 · Updated Oct 6, 2025
Authentication bypass in Tesla Telematics Control Unit firmware before 2025.14 allows physically proximate attackers to execute code as root. The /etc/launch_adbd lockdown blocks adb shell but leaves root-privileged adb push, pull, and port forwarding available over the exposed Micro USB port. Physical access to the unit is required; a planted executable path written to uevent_helper or hotplug runs when a kernel event is triggered.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
