"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfc: port100: reject frames whose declared length exceeds the received data\n\nport100_recv_response() passes the URB transfer buffer to\nport100_rx_frame_is_valid(), which checksums le16_to_cpu(frame->datalen)\nbytes of frame->data. datalen is a 16-bit field supplied by the device\nand is never checked against the number of bytes actually received\n(urb->actual_length), so a device reporting a datalen larger than the\nreceived frame makes port100_data_checksum() read out of bounds past the\ntransfer buffer.\n\nReject a response whose declared frame size does not fit the received\nlength before validating it.\n\nFound by 0sec (https://0sec.ai) using automated source analysis; the\nmissing bound is evident from source. Compile-tested."
