In mcm_read_packet() the length of the buffer received from media_proxy can be smaller than the configured frame size. Passing the size argument to memcpy() being larger than the source buffer size can lead to a segmentation fault. This commit fixes this issue by passing the size argument to memcpy() as the lowest value between the configured frame size and the actual Rx buffer length.
