Linux Debian vulnerability analysis and mitigation
Overview
CVE-2025-45512 is a security vulnerability discovered in DENX Software Engineering Das U-Boot (U-Boot) version 1.1.3. The vulnerability stems from a lack of signature verification in the bootloader, which was discovered in August 2025. This flaw affects the bootloader component of U-Boot systems, potentially impacting embedded systems and Raspberry Pi-based platforms (GitHub PoC).
Technical details
The vulnerability is classified as CWE-77 (Improper Neutralization of Special Elements used in a Command) with a CVSS v3.1 base score of 6.5 (Medium) and vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N. The technical issue lies in the bootloader's firmware verification mechanism, where the absence of proper signature validation allows for the manipulation of firmware files (NVD).
Impact
The vulnerability allows attackers to install crafted firmware files, leading to arbitrary code execution. The impact extends to potential firmware manipulation, unauthorized code execution, and system compromise. The affected components include the bootloader, firmware update mechanism, debug interfaces (UART, JTAG), SPI Flash Interface, and DDR Memory Calibration Subsystem (GitHub PoC).
