CVE-2026-57222
Publication date 18 September 2026
Last updated 23 September 2026
Ubuntu priority
Description
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.
