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 - Ted
