u-boot

u-boot-nezha

Das U-Boot versions before 2026.04 contain a vulnerability in the FIT (Flat Image Tree) signature verification process. The issue arises because the hashed-nodes component is omitted from the hash calculation, allowing an attacker to bypass signature verification. This flaw affects multiple specific versions of u-boot as listed. The vulnerability has a CVSS score of 8.8, indicating high impact on confidentiality, integrity, and availability. No explicit patch or remediation details are provided in the input data.

Das U-Boot before version 2026.04 has a vulnerability (CVE-2026-46728) in its FIT signature verification mechanism. The vulnerability is due to the omission of hashed-nodes from the hash calculation, which enables bypassing the signature verification. This can allow unauthorized modification or execution of unsigned code within the boot process. The vulnerability affects numerous specific versions of u-boot as enumerated. The CVSS 3.1 score is 8.8 (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), indicating a local attack vector with low complexity and privileges required, no user interaction, and a scope change with high impact on confidentiality, integrity, and availability.

Das U-Boot before 2026.04 allows FIT (Flat Image Tree) signature verification bypass because hashed-nodes is omitted from a hash. (CVE-2026-46728)

Das U-Boot before 2026.04 allows FIT (Flat Image Tree) signature verification bypass because hashed-nodes is omitted from a hash.

This vulnerability in denx U-Boot prior to version 2026.04 arises from an origin validation error (CWE-346) where the FIT signature verification process is flawed. Specifically, hashed-nodes are omitted from the hash, enabling signature verification bypass. The CVSS 3.1 score is 8.2, reflecting high impact on confidentiality, integrity, and availability, with attack vector local, low attack complexity, and requiring high privileges. The vulnerability affects the bootloader's ability to ensure the authenticity of boot images, potentially allowing malicious code execution during boot.
