Kernel oops in stub_send_ret_submit (usbip_host) when Windows client opens remote CH340 serial port on Raspberry Pi 3B

Start by locating stub_send_ret_submit in the kernel's USB/IP host implementation and review the kernel oops trace and USB/IP submit path described in the issue. Reproduce with the listed Raspberry Pi, CH340 adapter, and Windows USB/IP client if available. Done means opening the remote serial port no longer causes a kernel oops; the issue does not name a test file.

Describe the bug

A CH340 USB serial adapter is bound with usbip bind on Raspberry Pi and exported via USB/IP. The bind itself succeeds (stub up). However, when a Windows client connects to the exported device and opens the virtual serial port, the Raspberry Pi kernel oopses in stub_send_ret_submit inside the usbip_host module.

Steps to reproduce the behaviour

Step 1 — Raspberry Pi initialization

1. Raspberry Pi OS (2026-10-06 release, 64-bit, kernel 6.18.50, Debian 13 Trixie) on Raspberry Pi 3 Model B Rev 1.2.
2. Connect a CH340 USB serial adapter (VID:PID 1a86:7523).
3. Run the following commands
   sudo modprobe usbip_host
   sudo usbipd -D
   sudo usbip bind -b 1-1.5 # Replace 1-1.5 with the actual bus ID from usbip list -l

Step 2 — Windows USB/IP client

1. On a Windows client, install a USB/IP client usbip-win2.
2. Connect to the Raspberry Pi USB/IP server, list devices, and attach the exported CH340 device. This creates a virtual COM port on Windows.

Step 3 — Windows opens the mapped serial port

1. Open the mapped serial port using the https://www.winnermicro.com/upload/1/editor/1715417724904.rar.

Setp 4 — The kernel oops occurs on the Raspberry Pi side.
