Estado: AnalizadaAlta (7.8)—
Integer overflow or wraparound in Windows Hyper-V allows an authorized attacker to elevate privileges locally.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.46%
- Percentil entre todas las CVEs puntuadas: 38
- Fecha de la puntuación: 6/10/2026
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.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation95 % - Impacto principal
T1059Command and Scripting Interpreterexecution85 % - Impacto secundario
T1548Abuse Elevation Control Mechanismprivilege escalation75 %
Vector AV:L/PR:L/UI:N indica acceso local con privilegios limitados sin interacción: escalada de privilegios (T1068). Integer overflow en Hyper-V permite ejecución de código con máximos privilegios (T1059, T1548).
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.
