CVE-2026-9492

Estado: AplazadaAlta (8.5)—

The MBStorage DRAM lighting control module within Gigabyte Control Center (GCC) developed by GIGABYTE Technology has an Improper Access Control vulnerability. Authenticated local attackers can send specific IOCTL commands through the driver MyPortIO_x64.sys bundled with the module, thereby arbitrarily reading and writing physical memory and obtaining kernel-level privileges.

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 local (AV:L) con privilegios (PR:L) sin interacción: escalada vía driver. El atacante lee/escribe memoria física (T1005, T1565) y obtiene nivel kernel (T1068).

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.
