CVE-2024-20871

Factory reset protection bypass via context menu

Published May 7, 2024 · Updated Aug 1, 2024

Improper authorization in Samsung Keyboard before One UI 5.1.1 allows physically proximate attackers to partially bypass factory reset protection. A context menu remains usable during the protected setup state, and the patch blocks that menu to prevent the authorization bypass. Physical possession and user interaction are required; the disclosed consequence is limited to a partial bypass of factory reset protection.
