CVE-2026-21224

Estado: AnalizadaAlta (7.8)—

Stack-based buffer overflow in Azure Connected Machine Agent allows an authorized attacker to elevate privileges locally.

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:R indica escalada local. Buffer overflow (CWE-121) con PR:L permite ejecución de código y elevación a privilegios de administrador, confirmando T1068 como explotación e impactos en ejecución de comandos y acceso con credenciales elevadas.

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.
