Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/ipheth-1.0/ipheth-driver/ipheth.c Examining data/ipheth-1.0/ipheth-pair/ipheth-pair.c 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).
