Yeah -- Guillaume, I think that you are actually seeing symptoms of
intfdata being bogus. Could you please try with any kernel with commit
9c9e54a8df0be48 ("HID: hiddev: fix memory corruption due to invalid
intfdata") applied (which is the one Arnd is talking about) and report
back whether the problem is fixed by it?

Thanks,
