CVE-2025-1865

Estado: AplazadaAlta (8.5)—

The kernel driver, accessible to low-privileged users, exposes a function that fails to properly validate the privileges of the calling process. This allows creating files at arbitrary locations with full user control, ultimately allowing for privilege escalation to SYSTEM.

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 + PR:L sin UI permite escalada local sin interacción (T1068). Acceso a archivos arbitrarios y privilegios de SYSTEM sugieren lectura de datos y manipulación de cuentas.

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.
