CVE-2025-20991

Device discoverability changes via exported Bluetooth components

Published Jun 4, 2025 · Updated Jun 4, 2025

Improper component export in Bluetooth on Samsung Mobile Devices before SMR Jun-2025 Release 1 allows local attackers to enable discoverability. Bluetooth exposes Android application components without proper access control, allowing an unprivileged local application to invoke the discoverability operation. The attacker needs code execution on an affected Android 13, 14, or 15 device; the published impact is limited to changing its discoverable state.
