I agree the existing code (and this patch) is pretty cryptic for anyone not
familiar with FAT format.
However, I think it could be a good thing to first merge this one (which is correct, and works), and refactor this in a second time, so the current
ubsan issue is fixed upstream as soon as possible.
For an actual *fix*, please take a look at
https://lore.kernel.org/qemu-devel/20250119093233.9e4c450...@localhost.tls.msk.ru/
which is minimal, understandable, verified and works.
