I don't understand how that could happen. MCU reboots, ???, brake system segfaults? What goes in the middle?

  Probably everything has access to everything on the CAN bus. IIRC car manufactures are irresponsibly lazy and never properly air-gap infotainment from critical stuff.

    There's a firewall between the CAN bus so it cannot be affected at all by the MCU.

    Even if this were true (and as another commenter says, it's not) I don't see how that fills in this gap. It would make sense if the first step were "MCU goes crazy," but not with a simple reboot.
