CVE-2025-3052 is a critical Secure Boot vulnerability affecting Windows 11 and other modern Windows systems. Discovered by security researchers at Binarly, the flaw involves a legitimate BIOS update utility signed with Microsoft's UEFI CA 2011 certificate that reads a user-writable NVRAM variable without proper validation. This oversight allows attackers to bypass Secure Boot entirely, even on fully updated systems, enabling the installation of persistent bootkit malware. Microsoft has released a fix for CVE-2025-3052, but the vulnerability has raised concerns about the robustness of Secure Boot as a foundational security defense. Discussions on WindowsForum cover the technical details, exploit risks, and implications for enterprise IT and home users.
