Security readout for executives and security teams
Plain-English summary
CVE-2021-25406 is an information exposure issue in Samsung Mobile Gear S Plugin before version 2.2.05.20122441. The reported risk is that untrusted applications could access information about connected Bluetooth devices. The public sources do not provide CVSS, severity, exploit evidence, or detailed impact scope.
Executive priority
Track and remediate through normal mobile fleet hygiene unless the organization has high-risk wearable use cases or unmanaged app exposure. The lack of severity and exploitation evidence lowers urgency, but version compliance should still be confirmed.
Technical view
The CVE describes CWE-922 affecting Gear S Plugin versions prior to 2.2.05.20122441. The flaw allows untrusted applications to access connected BT device information. Available sources do not specify required privileges, attack complexity, affected platforms beyond the plugin, or the exact data fields exposed.
Likely exposure
Exposure is likely limited to devices with Samsung Mobile Gear S Plugin installed below version 2.2.05.20122441. Organizations should prioritize managed mobile fleets, users with Samsung wearable integrations, and endpoints where untrusted or unmanaged applications may coexist with the plugin.
Exploitation context
The source bundle does not show CISA KEV listing, active exploitation, public exploit availability, or in-the-wild abuse. Treat this as a confirmed vendor-disclosed information exposure issue, but do not assume exploitation without additional evidence.
Researcher notes
Evidence is sparse. The CVE names information exposure, CWE-922, a version boundary, and connected BT device information as the exposed asset. It does not describe exploit primitives, permissions, storage location, affected OS versions, or security patch mechanics.
Mitigation direction
- Update Gear S Plugin to version 2.2.05.20122441 or later.
- Check Samsung Mobile security guidance for any additional remediation instructions.
- Remove unneeded or untrusted applications from affected mobile devices.
- Apply mobile device management controls for app installation and wearable integrations.
Validation and detection
- Inventory devices with Gear S Plugin installed.
- Confirm installed plugin versions are 2.2.05.20122441 or later.
- Identify users with connected Samsung wearable or Bluetooth device workflows.
- Review managed device app lists for untrusted or unmanaged applications.
