In the Linux kernel, the following vulnerability has been resolved:
usb: musb: Fix musb_gadget.c rxstate overflow bug
The usb function device call musb_gadget_queue() adds the passed
request to musb_ep::req_list,If the (request->length > musb_ep->packet_sz)
and (is_buffer_mapped(req) return false),the rxstate() will copy all data
