Summary:
As of July 8, 2025 Microsoft has completed mitigations to address this vulnerability. See KB5042562: Guidance for blocking rollback of virtualization-based security related updates and the Recommended Actions section of this CVE for guidance on how to protect your systems from this vulnerability.
An elevation of privilege vulnerability exists in Windows based systems supporting Virtualization Based Security (VBS), including a subset of Azure Virtual Machine SKUS. This vulnerability enables an attacker with administrator privileges to replace current versions of Windows system files with outdated versions. By exploiting this vulnerability, an attacker could reintroduce previously mitigated vulnerabilities, circumvent some features of VBS, and exfiltrate data protected by VBS.
Update: July 10, 2025
Microsoft has addressed this vulnerability for Windows 10 1507, Windows 10, version 1607, Windows 10, version 1809, and Windows Server 2016 and Windows Server 2018. This ensures that mitigations are available to protect all supported versions of Windows 10 and Windows 11 from this vulnerability. See the available mitigations and deployment guidelines described in KB5042562: Guidance for blocking rollback of virtualization-based security related updates.
Update: August 13, 2024
Microsoft has released the August 2024 security updates that include an opt-in revocation policy mitigation to address this vulnerability. Customers running affected versions of Windows are encouraged to review KB5042562: Guidance for blocking rollback of virtualization-based security related updates to assess if this opt-in policy meets the needs of their environment before implementing this mitigation. There are risks associated with this mitigation that should be understood prior to applying it to your systems. Detailed information about these risks is also available in KB5042562.

New Windows Driver Signature bypass allows kernel rootkit installs

New Windows Driver Signature bypass allows kernel rootkit installs
## New Windows Driver Signature bypass allows kernel rootkit installs
## Bill Toulas
Attackers can downgrade Windows kernel components to bypass security features such as Driver Signature Enforcement and deploy rootkits on fully patched systems.
This is possible by taking control of the Windows Update process to introduce outdated, vulnerable software components on an up-to-date machine without the operating system changing the fully patched status.
## Downgrading Windows
SafeBreach security researcher Alon Leviev reported the update takeover issue but Microsoft dismissed it saying that it did not cross a defined security boundary, although was possible by gaining kernel code execution as an administrator.

Leviev has also shared multiple usage examples that allow downgrading the Hyper-V hypervisor (to a two-year-old version), Windows Kernel, the NTFS driver, and the Filter Manager driver (to their base versions), and other Windows components and previously applied security patches.
"You can use it to take over Windows Updates to downgrade and expose past vulnerabilities sourced in DLLs, drivers, the NT kernel, the Secure Kernel, the Hypervisor, IUM trustlets and more," SafeBreach security researcher Alon Leviev explained .
"Other than custom downgrades, Windows Downdate provides easy to use usage examples of reverting patches for CVE-2021-27090, CVE-2022-34709, CVE-2023-21768 and PPLFault, as well as examples fo

Leviev discovered that the Windows update process could be compromised to downgrade critical OS components, including dynamic link libraries (DLLs) and the NT Kernel. Even though all of these components were now out of date, when checking with Windows Update, the OS reported that it was fully updated, with recovery and scanning tools unable to detect any issues.
By exploiting the zero-day vulnerabilities, he could also downgrade Credential Guard's Secure Kernel and Isolated User Mode Process and Hyper-V's hypervisor to expose past privilege escalation vulnerabilities.
