CVE-2019-20570Network attack vector

Factory Reset Protection bypass via Smart Switch

Published Mar 24, 2020 · Updated Aug 5, 2024

Factory Reset Protection bypass in Samsung mobile devices on Android 7.1, 8.0, or 9.0 allows attackers to defeat post-reset ownership checks. The public record identifies Smart Switch as the bypass path but does not disclose the failed FRP check or the operation that handles untrusted input incorrectly. The device must be in the FRP-protected post-reset state and accessible through Smart Switch; the bounded impact is unauthorized activation rather than data access.
