CVE-2026-33243 barebox: FIT Signature Verification Bypass Vulnerability

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...

CVE-2026-33243

Barebox contains a vulnerability in the FIT signing flow: during mkimage, the hashed-nodes property of the FIT signature node is computed, but the hashed-nodes value is not itself protected by the hash. An attacker can modify hashed-nodes to influence which nodes were reported as hashed, potentia...
