CVE-2025-20996

Local data disclosure via missing authorization

Published Jun 4, 2025 · Updated Jun 4, 2025

Improper authorization in Samsung Smart Switch before 3.7.64.10 allows local users to read app-accessible data on non-Samsung devices. Samsung has not disclosed the affected component or the authorization check that accepts the user-triggered request. A low-privileged local attacker must induce user interaction; successful exploitation exposes only data that Smart Switch can read.
