About this tag
CVE-2025-2296 is a security vulnerability affecting the EDK2 firmware's OvmfPkg (Open Virtual Machine Firmware) component, specifically in its direct boot mode. The flaw allows a legacy loader to be used when Secure Boot signature verification fails, effectively bypassing Secure Boot protections. This could enable arbitrary pre-OS code execution if an attacker has sufficient privileges. The vulnerability is relevant to systems using EDK2-based firmware, particularly in virtualized environments. Discussions on WindowsForum cover the technical details, potential impact, and mitigation strategies for this Secure Boot bypass.

  1. CVE-2025-2296: Secure Boot Bypass in EDK2 OVMF Direct Boot

    When Secure Boot is supposed to be the safety net that stops unsigned code from running before the operating system, a small logic shortcut in the firmware can erase that protection — and that is precisely what the newly published CVE-2025-2296 describes: an EDK2/OvmfPkg flaw that can let a...
