{"schemaVersion":3,"id":"CVE-2026-45747","aliases":["UBUNTU-CVE-2026-45747","DEBIAN-CVE-2026-45747"],"status":"published","duplicateOf":null,"title":"Suricata lua/tls: null dereference in TlsGetCertInfo","description":"Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.16, the Lua TLS certificate information helper could dereference NULL certificate fields when a Lua script requested certificate information for TLS traffic where some certificate fields were absent. Crafted TLS traffic processed by a deployment using affected Lua TLS scripting could crash Suricata, resulting in denial of service. Version 7.0.16 contains a fix. As a workaround, avoid Lua scripts that call TLS certificate information helpers on untrusted traffic (`TlsGetCertInfo` function), or update scripts to handle missing certificate fields where possible.","dates":{"published":"2026-09-10T14:17:44.236Z","modified":"2026-09-10T16:26:18.836Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.5,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"OSV
