CVE-2026-105043

Estado: Pendiente de análisisBaja (3.6)—

MathWorks Simulink before R2026b, when showing a crafted .slx file, can have blocks that are never visible in the Simulink Editor but will cause code execution.

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 + UI:R + apertura de archivo .slx preparado = ejecución de código en cliente; CWE-451 (inicialización inapropiada) sugiere ejecución mediante bloques ocultos en Simulink.

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.
