Haven't seen a Linux driver for that 'some USB card' yet.

I already conceded that's possible.
So our problem with the bug Al spotted, and AFFS on USB media are twtofold:
Exploitable: yes (unless the AmigaOS AFFS driver detects and mitigates this).
Likelihood: low (as Joanne said there are easier ways to do harm to
Exploitable: yes, except on hardware that doesn't have USB hardware support.
Can we blacklist affs from being autoloaded through udev on USB
