Unpatchable AMD Chip Flaw Unlocks Paid Tesla Feature Upgrades

Sorry Elon, but this jailbreak appears to be unpatchable.
Now, a team of security researchers from TU Berlin has found a way to exploit or "jailbreak" the MCU found in modern Tesla vehicles to unlock paid features and more. To execute the attack, the researchers exploited a known flaw in AMD's processor that controls Tesla's MCU.
Our gained root permissions enable arbitrary changes to Linux that survive reboots and updates. They allow an attacker to decrypt the encrypted NVMe storage and access private user data such as the phonebook, calendar entries, etc. On the other hand, it can also benefit car usage in unsupported regions. Furthermore, the ASP attack opens up the possibility of extracting a TPM-protected attestation key Tesla uses to authenticate the car. This enables migrating a car's identity to another car computer without Tesla's help whatsoever, easing certain repairing efforts.
