Detailsinfo

A vulnerability classified as critical has been found in OISF Suricata up to 8.0.5. This affects an unknown code of the file src/datasets-context-json.c of the component Datasets. The manipulation of the argument value_key with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-57225 since 06/24/2026. The exploitability is told to be easy.
