Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to 7.0.17 and 8.0.6, crafted IPv4 and IPv6 address pairs can collide in the IPPair hash because src/ippair.c did not compare the IP address family before reusing IPPair-backed state. This can apply state from one IP family to another for xbits track ip_pair, FTP data expectations, and, on the 7.0 release line, thresholding, detection_filter, and rate_filter rules using track by_both, causing incorrect detection state. This issue is fixed in versions 8.0.6 and 7.0.17.
CVE-2026-57222
MEDIUMPre-NVD 5.35.3
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 5.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
