CVE-2026-20972

Local UWB enablement via unprotected exported component

Published Jan 9, 2026 · Updated Jan 9, 2026

Improper component export in Samsung Mobile Devices before SMR Jan-2026 Release 1 allows local users to enable UWB through UwbTest. Samsung identifies UwbTest as the locus but does not disclose which exported component lacks the required permission or how it invokes the UWB operation. A low-privilege local context is required, and the reported consequence is limited to unauthorized UWB enablement.
