TOCTOU?
I found your paper very interesting. It's a bit depressing that Tesla have made all the same old mistakes!

One thing I noticed:

"Gateway checks the signature of the updater, which is the file boot.img. Once it is passed, gateway will turn into the update mode, load the boot.img file into ram and execute it."

It sounds like there might be a classic TOCTOU vulnerability there where boot.img could be replaced between check and loading into RAM. What do you think?
