If you can get control over a spi or spio bus, then of course all bets are off, that is not the Linux security model at all. So if you care about invalid data on that bus, please work on auditing and fixing up all kernel drivers for that subsystem as this is a totally new threat model that no one has ever handled for this operating system (and one that no one ever said we were secure from.) thanks, greg k-h
