CVE-2026-7162

Estado: AplazadaAlta (7.8)—

Successful exploitation of the integer overflow vulnerability could allow an attacker to achieve system-level access to the affected software.

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.

AV:L sin UI y PR:L indica escalada de privilegios local. Integer overflow (CWE-190) en contexto de acceso local lleva a ejecución de código con privilegios elevados.

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.
