Description
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 in fifo to request->buf which may cause request->buf out of bounds. Fix it by add the length check : fifocnt = min_t(unsigned, request->length - request->actual, fifocnt);
