A vulnerability has been found in Host Boot ROM (affected version unknown) and classified as critical. Affected by this vulnerability is an unknown functionality of the component UFS. The manipulation with an unknown input leads to a security-sensitive hardware controls with missing lock bit protection vulnerability. The CWE definition for the vulnerability is CWE-1233. The 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was shared 01/24/2023. It is possible to read the advisory at westerndigital.com. This vulnerability is known as CVE-2022-23005 since 01/10/2022. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
