From 8.0.0 until 8.0.6, src/datasets-context-json.c assumes that a configured JSON or NDJSON dataset value_key resolves to a string. A trusted or untrusted dataset or rule feed containing a non-string value for that key can cause a NULL pointer dereference during startup, configuration test mode, or rule reload, crashing Suricata before traffic processing. This issue is fixed in version 8.0.6.","published":"2026-09-18T21:17:01.000Z","lastModified":"2026-09-28T18:35:20.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-476"],"affected":["oisf/suricata"],"epss":{"score":0.00167,"percentile":0.05914,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.17%).
