CVE-2026-57225

Engine crash via non-string dataset value

Published Sep 18, 2026 · Updated Sep 18, 2026

NULL pointer dereference in Suricata 8.0.0 through 8.0.5 allows local users to crash the engine via a crafted JSON or NDJSON dataset. In src/datasets-context-json.c, dataset loaders pass a non-string value_key result through json_string_value and then use the resulting NULL pointer as a string. Exploitation requires the ability to supply or modify a loaded dataset or rule feed, and the crash occurs during startup, configuration testing, or rule reload before traffic processing.
