In the Linux kernel, the following vulnerability has been resolved:
media: mceusb: Use new usb_control_msg_*() routines
Automatic kernel fuzzing led to a WARN about invalid pipe direction in the mceusb driver:

The reason for the warning is clear enough; the driver sends an unusual read request on endpoint 0 but does not set the USB_DIR_IN bit in the bRequestType field.
More importantly, the whole situation can be avoided and the driver simplified by converting it over to the relatively new usb_control_msg_recv() and usb_control_msg_send() routines. That's what this fix does.
