CVE-2020-10846

Unauthorized custom binary loading via OEM unlock

Published Mar 24, 2020 · Updated Aug 4, 2024

Improper authentication in Samsung mobile devices with Android 9.x or 10.x allows local users to enable OEM unlock and load custom binaries. The OEM unlock verification logic fails to enforce the KG enrollment restriction under certain conditions. The issue is limited to selected KG-enrolled devices and requires local low-privileged access; it permits unauthorized binary loading rather than direct data access.
