La función walk_hugetlb_range en mm/pagewalk.c en el kernel de Linux en versiones anteriores a la 4.14.2 gestiona de manera incorrecta los agujeros en los rangos hugetlb, lo que permite que usuarios locales obtengan información sensible de la memoria del kernel no inicializada mediante el uso manipulado de la llamada del sistema mincore().

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.
