Thanks for the report!  I've opened

   https://bugzilla.kernel.org/show_bug.cgi?id=215225

to track this report.

(In my experience fuzzing reports can a while to resolve, since folks
work on them on a as-time-available-basis.  So in order to make sure
we don't lose track of any of them, I'm using bugzilla.kernel.org.
Fell free to submit feature fuzzing reports using the File systems /
ext4 component, and please prefix the bug title with "FUZZ: ", e.g.

FUZZ: Page fault and infinite loop after mount and operate on crafted image
