Descriptions

Western Digital has identified a weakness in the UFS standard that could result in a security vulnerability. This vulnerability may exist in some systems where the Host boot ROM code implements the UFS Boot feature to boot from UFS compliant storage devices. The UFS Boot feature, as specified in the UFS standard, is provided by UFS devices to support platforms that need to download the system boot loader from external non-volatile storage locations. Several scenarios have been identified in which adversaries may disable the boot capability, or revert to an old boot loader code, if the host boot ROM code is improperly implemented. UFS Host Boot ROM implementers may be impacted by this vulnerability. UFS devices are only impacted when connected to a vulnerable UFS Host and are not independently impacted by this vulnerability. When present, the vulnerability is in the UFS Host implementation and is not a vulnerability in Western Digital UFS Devices. Western Digital has provided details of the vulnerability to the JEDEC standards body, multiple vendors of host processors, and software solutions providers.

Western Digital ha identificado una debilidad en el estándar UFS que podría resultar en una vulnerabilidad de seguridad. Esta vulnerabilidad puede existir en algunos sistemas donde el código ROM de inicio del host implementa la función de inicio UFS para iniciar desde dispositivos de almacenamiento compatibles con UFS. La función de arranque UFS, como se especifica en el estándar UFS, la proporcionan los dispositivos UFS para admitir plataformas que necesitan descargar el cargador de arranque del sistema desde ubicaciones de almacenamiento externas no volátiles. Se han identificado varios escenarios en los que los adversarios pueden desactivar la capacidad de arranque o volver a un código de cargador de arranque antiguo, si el código ROM de arranque del host se implementa incorrectamente. Los implementadores de UFS Host Boot ROM pueden verse afectados por esta vulnerabilidad. Los dispositivos UFS solo se ven afectados cuando están conectados a un host UFS vulnerable y esta vulnerabilidad no los afecta de forma independiente. Cuando está presente, la vulnerabilidad está en la implementación del host UFS y no es una vulnerabilidad en los dispositivos UFS de Western Digital. Western Digital ha proporcionado detalles de la vulnerabilidad al organismo de estándares JEDEC, a múltiples proveedores de procesadores host y proveedores de soluciones de software.
