About this tag
CVE-2024-21302 is a Windows Secure Kernel Mode Elevation of Privilege Vulnerability that also enables downgrade attacks on Virtualization-Based Security (VBS) in Windows 10 and 11. Microsoft addressed this flaw in an August 2024 Patch Tuesday update, but researchers demonstrated that the vulnerability could be exploited to revert fully patched systems to older, exploitable states without user awareness. The attack, known as the Windows Downdate attack, bypasses Windows Update safeguards and can permanently downgrade critical OS components. Discussions on WindowsForum cover the technical details of CVE-2024-21302, its relation to VBS rollback, and the broader implications for enterprise security, including advisories from CERT-In and presentations at Black Hat 2024.
