CVE-2018-12904

Estado: ModificadaMedia (4.9)—💥 Exploit

En arch/x86/kvm/vmx.c en el kernel de Linux en versiones anteriores a la 4.17.2, cuando se emplea la virtualización anidada, los atacantes locales podrían hacer que los invitados L1 KVM realizasen un VMEXIT, permitiendo escalados de privilegios y ataques de denegación de servicio (DoS) debido a la falta de comprobación de CPL.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
