CVE-2021-25467

Estado: ModificadaMedia (6.7)—

Suponiendo que se obtenga el privilegio del sistema, una posible vulnerabilidad de desbordamiento de búfer en el controlador del kernel de Vision DSP versiones anteriores a SMR Oct-2021 Release 1, permite una escalada de privilegios a Root mediante el secuestro de la biblioteca cargada

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).
