A vulnerability in the bootloader of DENX Software Engineering Das U-Boot (U-Boot) version 1.1.3 allows attackers to install crafted firmware files due to a lack of signature verification. This flaw can lead to arbitrary code execution. The issue affects multiple specific Ubuntu package versions of U-Boot. The CVSS score is 6.5, indicating a medium severity level.

CVE-2025-45512 describes a security vulnerability in the bootloader of DENX Software Engineering Das U-Boot (U-Boot) version 1.1.3, where the bootloader does not verify signatures on firmware files. This lack of signature verification enables attackers to install maliciously crafted firmware, potentially resulting in arbitrary code execution on affected systems. The vulnerability affects numerous specific Ubuntu package versions of U-Boot as listed. The CVSS 3.1 base score is 6.5 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, and limited confidentiality and integrity impact without availability impact.

A lack of signature verification in the bootloader of DENX Software Engineering Das U-Boot (U-Boot) v1.1.3 allows attackers to install crafted firmware files, leading to arbitrary code execution.

CVE-2025-45512 is a medium-severity vulnerability affecting the bootloader component of DENX Software Engineering's Das U-Boot (U-Boot) version 1.1.3. The vulnerability arises due to a lack of signature verification during the firmware loading process in the bootloader. Specifically, the bootloader does not verify cryptographic signatures on firmware files before installation, allowing an attacker to supply crafted firmware images. This flaw enables arbitrary code execution at the bootloader level, which is a critical stage in the device startup sequence. Exploiting this vulnerability requires no authentication or user interaction and can be performed remotely over a network if the bootloader firmware update interface is exposed. The CVSS 3.1 base score is 6.5 (medium), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N, indicating network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, and limited confidentiality and integrity impacts without availability impact. The weakness is categorized under CWE-77, which relates to improper neutralization of special elements used in a command ('Command Injection'). Although no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the critical nature of bootloader code execution and the potential for persistent compromise. No patches or mitigations are currently linked, highlighting the need for immediate attention from affected parties.
