CVE-2023-21252

Estado: ModificadaMedia (5.5)—

En validarPassword de WifiConfigurationUtil.java, existe una forma posible de hacer que el dispositivo entre en un bucle de arranque debido a una validación de entrada incorrecta. Esto podría provocar una denegación de servicio local sin necesidad de privilegios de ejecución adicionales. La interacción del usuario no es necesaria para la explotación.

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).
