Vulnerability Title
barebox: FIT Signature Verification Bypass Vulnerability
Vulnerability Description
barebox is a bootloader. In barebox from version 2016.03.0 to before version 2026.03.1 (and the corresponding backport to 2025.09.3), an attacker could exploit a FIT signature verification vulnerability to trick the bootloader into booting different images than those that were verified as part of a signed configuration. mkimage(1) sets the hashed-nodes property of the FIT signature node to list which nodes of the FIT were hashed as part of the signing process as these will need to be verified later on by the bootloader. However, hashed-nodes itself is not part of the hash and could therefore be modified to allow booting different images than those that have been verified. This issue has been patched in barebox versions 2026.03.1 and backported to 2025.09.3.

Vulnerability Title
Barebox 数据伪造问题漏洞
Vulnerability Description
Barebox是Barebox开源的一个多功能且灵活的引导加载程序。 Barebox 2025.09.3之前版本和2026.03.1之前版本存在数据伪造问题漏洞，该漏洞源于创建FIT时，mkimage设置的hashed-nodes属性未包含在哈希中，可能导致攻击者修改该属性以欺骗引导加载程序启动未经验证的镜像。
