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

nfc: port100: reject frames whose declared length exceeds the received data

port100_recv_response() passes the URB transfer buffer to
port100_rx_frame_is_valid(), which checksums le16_to_cpu(frame->datalen)
bytes of frame->data. datalen is a 16-bit field supplied by the device
and is never checked against the number of bytes actually received
(urb->actual_length), so a device reporting a datalen larger than the
received frame makes port100_data_checksum() read out of bounds past the
transfer buffer.

Reject a response whose declared frame size does not fit the received
length before validating it.

Found by 0sec (https://0sec.ai) using automated source analysis; the
missing bound is evident from source. Compile-tested.
