CVE-2026-57225: Oisf Suricata

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. 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.

Affected products

• Oisf Suricata: from 8.0.0, before 8.0.6 (fixed in 8.0.6)
