CVE-2022-23005 – Host Boot ROM Code Vulnerability in Systems Implementing UFS Boot Feature

https://notcve.org/view.php?id=CVE-2022-23005

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. • https://documents.westerndigital.com/content/dam/doc-library/en_us/assets/public/western-digital/collateral/white-paper/white-paper-host-boot-rom-code-vulnerability-and-mitigation.pdf https://www.westerndigital.com/support/product-security/wdc-23001-host-boot-rom-code-vulnerability-in-systems-implementing-ufs-boot-feature • CWE-662: Improper Synchronization CWE-1224: Improper Restriction of Write-Once Bit Fields CWE-1233: Security-Sensitive Hardware Controls with Missing Lock Bit Protection CWE-1262: Improper Access Control for Register Interface •
