Description

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.

• CWE-1224Improper Restriction of Write-Once Bit FieldsThe hardware design control register "sticky bits" or write-once bit fields are improperly implemented, such that they can be reprogrammed by software.
• CWE-1233Security-Sensitive Hardware Controls with Missing Lock Bit ProtectionThe product uses a register lock bit protection mechanism, but it does not ensure that the lock bit prevents modification of system registers or controls that perform changes to important hardware system configuration.
• CWE-1262Improper Access Control for Register InterfaceThe product uses memory-mapped I/O registers that act as an interface to hardware functionality from software, but there is improper access control to those registers.
• CWE-662Improper SynchronizationThe product utilizes multiple threads, processes, components, or systems to allow temporary access to a shared resource that can only be exclusive to one process at a time, but it does not properly synchronize these actions, which might cause simultaneous accesses of this resource by multiple threads or processes.
