CVE-2026-40144

Estado: Pendiente de análisisAlta (7.3)—

A memory-corruption vulnerability exists in a kernel-mode component of BeyondTrust Endpoint Privilege Management (Windows deployments) prior to version 26.1.2. Insufficient validation of input processed by the component may result in memory being accessed outside its intended bounds.

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 con AV:L y PR:L sin interacción del usuario (UI:N) indica escalada de privilegios local. CWE-125 (lectura fuera de límites) en componente kernel permite ejecución de código con privilegios elevados. Producto de gestión de privilegios afectado.

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.
