I guess thats overly dramatic. The big touchscreen (and I guess the only thing that actually runs a Linux) is called an infotainment system for a reason - it's absolutely non-critical to the operation of the vehicle. In fact, theres a hotkey on the steering wheel controls to reboot it :) All the critical systems are controlled by embedded systems running either no operating system at all or realtime operating systems that have been formally verified to some degree.

But they're all wired together with CANBus and similar interconnections. I don't exactly remember the details, but some researchers were able to kill acceleration with a MP3 on a CD rom, which exploited a buffer overflow and then sent malicious commands on the CANbus.
