rtl8139: skip offload on short TCP header (CVE-2015-5165) TCP Large Segment Offload accesses the TCP header in the packet. If the packet is too short we must not attempt to access header fields: tcp_header *p_tcp_hdr = (tcp_header*)(eth_payload_data + hlen); int tcp_hlen = TCP_HEADER_DATA_OFFSET(p_tcp_hdr); Reported-by: 朱东海(启路) <donghai.zdh@alibaba-inc.com> Reviewed-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
