CVE-2021-25416

Estado: ModificadaMedia (6.5)—

Asumiendo que EL1 esté comprometido, una comprobación de direcciones inapropiada en RKP anterior a la versión SMR JUN-2021 Release 1 permite a atacantes locales crear una página del kernel ejecutable fuera del área de código

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).
