{"id":"DEBIAN-CVE-2026-22264","details":"Suricata is a network IDS, IPS and NSM engine. Prior to version 8.0.3 and 7.0.14, an unsigned integer overflow can lead to a heap use-after-free condition when generating excessive amounts of alerts for a single packet. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not run untrusted rulesets or run with less than 65536 signatures that can match on the same packet.","modified":"2026-09-14T17:02:50.978688866Z","published":"2026-01-27T19:16:14.640Z","upstream":["CVE-2026-22264"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-22264"}],"affected":[{"package":{"name":"suricata","ecosystem":"Debian:13","purl":"pkg:deb/debian/suricata?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:7.0.10-1+deb13u3"}]}],"versions":["1:7.0.10-1","1:7.0.10-1+deb13u1","1:7.0.10-1+deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-22264.json"}},{"package":{"name":"suricata","ecosystem":"Debian:14","purl":"pkg:deb/debian/suricata?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:8.0.3-1"}]}],"versions":["1:7.0.10-1","1:7.0.11-1","1:7.0.11-1~bpo13+1","1:8.0.0-1~exp1","1:8.0.0-1~exp2","1:8.0.0-1~exp4","1:8.0.0-1~exp5","1:8.0.1-1","1:8.0.1-2","1:8.0.1-3","1:8.0.1-3~bpo13+1","1:8.0.2-1","1:8.0.2-1~bpo13+1","1:8.0.3-1~bpo13+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-22264.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"}]}
