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.
