CVE-2026-35553

Estado: Pendiente de análisisAlta (8.4)—

Bluetooth ACPI Drivers provided by Dynabook Inc. contain a stack-based buffer overflow vulnerability. An attacker may execute arbitrary code by modifying certain registry values.

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 sin UI:N y PR:H indican explotación local con privilegios (T1068). CWE-121 (buffer overflow) y descripción de ejecución arbitraria de código sustentan impacto T1059.

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.
