suricata: Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine
CVE-2026-71855 is fixed in suricata on 1 platform by DEBIAN-CVE-2026-71855 (version 1:8.0.6-1), released September 19, 2026. It is not reported as exploited. Patch Radar priority: High.
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, src/flow-hash.c can treat an IPv4 and IPv6 flow as equal without comparing the IP family when their raw address words, ports, protocol, VLAN, recursion level, live device, and hash bucket align. An IPv6 packet can therefore reuse IPv4 flow state or the reverse, causing incorrect flowbit state, detection bypass, or IP-only bypass. This issue is fixed in versions 8.0.6 and 7.0.17.
