Since arg is a user pointer, accessing values like cmd->iop requires an unsafe user pointer dereference.

Yes, you're right...

QUESTION: Does ioctl_passthru mean arg is a kernel pointer? If so, then
disregard this bug report.

No, arg is a user pointer...

Let me know if you have any questions, and thanks for looking into this.

No, thank you for taking your time, and also making the patch :-)



Best regards,
