CVE-2026-94424

Estado: AplazadaCrítica (9.3)—

A vulnerability has been found in Moore Threads MTT S80 Driver Package up to 340.150. Impacted is the function sub_140001000 in the library mtdispkm64.sys of the component IOCTL Handler. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The vendor was contacted early about this disclosure but did not respond in any way.

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.

Buffer overflow en controlador de kernel (mtdispkm64.sys) con acceso local y privilegios requeridos (PR:L) permite escalada de privilegios (VC:H/VI:H/VA:H) y ejecución de código. CWE-119/122 confirman overflow.

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.
