CVE-2022-21778

Estado: ModificadaMedia (6.7)—

En vpu, existe una posible divulgación de información debido a una verificación de los límites incorrecta. Esto podría conducir a una escalada local de privilegios con permisos de ejecución del System necesarios. La interacción del usuario no es necesaria para la explotación. ID de parche: ALPS06382421; ID del problema: ALPS06382421.

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).
