cve-program · CVE-2026-63451

Published

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, a locally supplied detection rule that combines frame inspection without content and a transformed match without content can make src/detect-engine-prefilter.c select multiple non-prefilter frame engines while preparing signatures for non-prefilter inspection. Loading the crafted rule, including in test mode, can trigger a heap buffer overflow and crash Suricata; network traffic alone cannot reach the flaw. This issue is fixed in version 8.0.6.
