In the Linux kernel, the following vulnerability has been resolved:

usb: musb: Fix musb_gadget.c rxstate overflow bug

The usb function device call musbgadgetqueue() adds the passed request to musbep::reqlist,If the (request->length > musbep->packetsz) and (isbuffermapped(req) return false),the rxstate() will copy all data in fifo to request->buf which may cause request->buf out of bounds.
