The article claims this is not patchable but it also says that the hackers have not yet unlocked FSD with this technique. I strongly suspect that the “unpatchable” part would not apply to any potential FSD unlock because of the large amount of server-side functionality involved for FSD. Server side components aren’t going to be easily fooled by a car-local exploit.

Knowing Tesla, even if they can’t patch the vulnerability OTA I would be very concerned about their being able to detect the use of this bypass and remote-brick cars in response until the customer agrees to bring their car in for a hardware patch.
