CVE-2025-14302

Estado: AplazadaAlta (7)—

Certain motherboard models developed by GIGABYTE has a Protection Mechanism Failure vulnerability. Because IOMMU was not properly enabled, unauthenticated physical attackers can use a DMA-capable PCIe device to read and write arbitrary physical memory before the OS kernel and its security features are loaded.

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.

Acceso físico (AV:P) a BIOS/firmware mediante DMA sin protección IOMMU permite leer/escribir memoria física. Impactos: exfiltración de datos pre-arranque y manipulación de memoria antes de cargar el kernel.

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.
