Thanks for the quick response. Indeed, the commit ffd603f21423
("usb: gadget: u_serial: Add null pointer check in gs_start_io")
solves the problem. Sorry for not checking the newest version.

I wonder whether it should also be applied to the LTS v5.15.167.
The bug is still present there.

Best Regards
Hubert
