FINAL RESULTS:

data/ipheth-1.0/ipheth-driver/ipheth.c:205:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(skb_put(skb, len), buf + NET_IP_ALIGN, len - NET_IP_ALIGN);
data/ipheth-1.0/ipheth-driver/ipheth.c:289:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(net->dev_addr, dev->ctrl_buf, ETH_ALEN);
data/ipheth-1.0/ipheth-driver/ipheth.c:359:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(dev->tx_buf, skb->data, skb->len);
