CVE-2020-16938

Estado: ModificadaMedia (5.5)—💥 PoC

Se presenta una vulnerabilidad de divulgación de información cuando el kernel de Windows maneja inapropiadamente objetos en memoria, también se conoce como "Windows Kernel Information Disclosure Vulnerability". Este ID de CVE es diferente de CVE-2020-16901

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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
