Security readout for executives and security teams
Plain-English summary
CVE-2021-25401 is a Samsung Health issue fixed before version 6.16. A malicious app or attacker path could redirect an Android intent so Samsung Health performs a privileged action it should not expose. The public record does not provide a CVSS score, exploit details, or evidence of active exploitation.
Executive priority
Prioritize remediation for managed Samsung mobile fleets, especially regulated or high-risk users. This is not currently supported as an emergency KEV-style response, but outdated Samsung Health versions should be removed from enterprise exposure.
Technical view
The CVE describes an intent redirection vulnerability in Samsung Health before 6.16, mapped to CWE-20 improper input validation. The reported impact is execution of a privileged action through Samsung Health. Public data does not specify affected Android versions, attack prerequisites, permissions required, or the exact privileged action.
Likely exposure
Exposure is limited to Samsung devices or environments where Samsung Health earlier than version 6.16 is installed. Organizations managing mobile fleets should treat this as mobile application exposure rather than server-side infrastructure risk.
Exploitation context
CISA KEV is false in the supplied bundle, and no cited source states active exploitation. The public description is sparse, so practical exploitability, required user interaction, and realistic attacker positioning remain unclear.
Researcher notes
The public record names intent redirection and privileged action execution but omits the vulnerable component, intent flow, permissions, and patch diff. Validation should remain version-based unless Samsung or another cited source provides deeper technical indicators.
Mitigation direction
- Upgrade Samsung Health to version 6.16 or later.
- Check Samsung Mobile May 2021 guidance for vendor-specific remediation details.
- Use MDM to identify and update outdated Samsung Health installations.
- Remove or disable outdated Samsung Health where updating is not possible.
Validation and detection
- Inventory managed devices for Samsung Health installations.
- Verify installed Samsung Health versions are 6.16 or later.
- Confirm the issue against Samsung’s May 2021 security advisory.
- Document any devices that cannot update and track compensating controls.

Improper Input Validation
Improper Input Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
