CVE-2026-0870

Estado: AplazadaAlta (8.5)—

MacroHub developed by GIGABYTE has a Local Privilege Escalation vulnerability. Due to the MacroHub application launching external applications with improper privileges, allowing authenticated local attackers to execute arbitrary code with SYSTEM 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.

AV:L (acceso local) + PR:L (privilegios requeridos) + UI:N (sin interacción) + VC:H/VI:H/VA:H (confidencialidad, integridad, disponibilidad altas) = escalada de privilegios local (T1068). La aplicación MacroHub ejecuta aplicaciones externas con privilegios SYSTEM impropiamente.

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.
