bootloader vulnerabilities

About this tag
Bootloader vulnerabilities are a critical security concern for systems ranging from enterprise servers to embedded devices. Recent discussions on WindowsForum highlight flaws in U-Boot, GRUB, and other bootloaders that can allow attackers to execute arbitrary code at boot time, bypass Secure Boot, or compromise early platform initialization. Notable examples include CVE-2025-24857 affecting Qualcomm IPQ devices and AI-driven discoveries by Microsoft uncovering over 20 vulnerabilities in GRUB2, U-Boot, and Barebox. These issues underscore the importance of keeping bootloaders updated and understanding their role in system security, especially for dual-boot setups and IoT devices.
