u-boot: CVE-2018-3968

Severity: Medium
Published: Mar 21, 2019, 5:29:00 PM UTC
Source: [NVD] · [CVE record]
EPSS: 0.28% · Oct 27, 2026

An exploitable vulnerability exists in the verified boot protection of the Das U-Boot from version 2013.07-rc1 to 2014.07-rc2. The affected versions lack proper FIT signature enforcement, which allows an attacker to bypass U-Boot's verified boot and execute an unsigned kernel, embedded in a legacy image format. To trigger this vulnerability, a local attacker needs to be able to supply the image to boot.
