In the Linux kernel, the following vulnerability has been resolved:
net: USB: Fix wrong-direction WARNING in plusb.c
The syzbot fuzzer detected a bug in the plusb network driver: A zero-length control-OUT transfer was treated as a read instead of a write. In modern kernels this error provokes a WARNING:

The fix is to call usbnet_write_cmd() instead of usbnet_read_cmd() and remove the USB_DIR_IN flag.
