This option allows AF_PACKET to re-assemble fragmented packets before reaching Suricata. However, because the default packet size in Suricata is based on the network interface MTU, Suricata can end up seeing truncated packets. If an attacker sends a maliciously fragmented packet, it can achieve a successful exploit.<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-1688587583\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>Below is a conceptual example of how the vulnerability might be exploited. This is a simple script that sends fragmented packets to a target:<\/p>\n<pre><code class=\"\" data-line=\"\">import socket\ntarget_ip = &quot;target.example.com&quot;\npacket = b&quot;malicious_payload&quot;\nsock = socket.socket(socket.AF_INET, socket.SOCK_RAW, socket.IPPROTO_RAW)\nsock.sendto(packet, (target_ip, 0))<\/code><\/pre>\n<p>This script sends a raw packet to a target IP.
