Prior to versions 7.0.16 and 8.0.5, DNP3 reassembly could buffer data without sufficient parser-level bounds. Crafted DNP3 traffic may cause Suricata to consume excessive memory, potentially resulting in denial of service. Versions 7.0.16 and 8.0.5 contain a fix. As a workaround, disable DNP3 (which is not enabled by default) if it is not needed, and/or define a limited `stream.reassembly.depth` (0 or absent is unlimited).","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400","CWE-770"],"references":["https://forum.suricata.io/t/suricata-8-0-5-and-7-0-16-released/6315","https://github.com/OISF/suricata/security/advisories/GHSA-m8x4-c78g-r4vj","https://redmine.openinfosecfoundation.org/issues/8460"],"products":["oisf:suricata"],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-45765","score":0.00616,"percentile":0.49539,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
