CVE-2026-8917

Estado: AplazadaAlta (8.4)—

Untrusted Pointer Dereference in ASUS GPU Tweak III, GPUTweakII, AI Suite3, and VGAdll: An IOCTL vulnerability allows a local attacker to write a specific value to an arbitrary memory address, potentially leading to privilege escalation. Refer to the '  Security Update for ASUS GPU Tweak III, GPU Tweak II, AI Suite 3, and Armoury Crate Security Bulletin   ' section on the ASUS Security Advisory for more information.

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.

Vector CVSS 4.0 con AV:L, PR:H indica acceso local con privilegios altos. La vulnerabilidad IOCTL permite escritura en memoria arbitraria para escalada de privilegios (CWE-822: Untrusted Pointer Dereference), típico de T1068. El impacto T1548 refleja la escalada de privilegios mencionada explícitame

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.
