In this case all users would equally be affected (and are, who knows how
many unknown bugs the CPU has), but the chance of someone using an
unknown CPU bug to break into a particular system is really small.

OTOH, a chance that someone who already broke into a system will do that
again (with flash ROMs etc. especially modified for this purpose during
the first break-in) may be considerable.
