CVE-2023-21485

Sandboxed media disclosure via exported VideoPreviewActivity

Published May 4, 2023 · Updated Feb 12, 2025

Improper component export in Samsung Mobile Devices before SMR May-2023 Release 1 allows physical attackers to access sandboxed media data. Call Settings exposes VideoPreviewActivity as an exported Android component, allowing external invocation across the intended sandbox boundary. Physical access to a device running Android 11, 12, or 13 is required, and the reported consequence is limited to reading some stored media data.
