CVE-2026-22264

Estado: AnalizadaCrítica (9.1)—

Suricata is a network IDS, IPS and NSM engine. Prior to version 8.0.3 and 7.0.14, an unsigned integer overflow can lead to a heap use-after-free condition when generating excessive amounts of alerts for a single packet. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not run untrusted rulesets or run with less than 65536 signatures that can match on the same packet.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vector CVSS N/N/L, sin autenticación requerida, apunta a explotación remota (T1190). El heap UAF (CWE-416) en procesamiento de paquetes permite RCE o DoS; la confianza en T1059 es moderada (el texto menciona 'code execution' implícito en UAF pero no lo explicita); T1499.004 por denial of service med

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
