CVE-2026-34859

Estado: AnalizadaAlta (7.1)—

UAF vulnerability in the kernel module. Impact: Successful exploitation of this vulnerability will affect availability and confidentiality.

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.

UAF en módulo kernel con AV:L (acceso local) y PR:L (requiere usuario local). Impactos: confidentiality (C:H) → lectura de datos T1005; availability (A:H) → DoS T1499.004.

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.
