CVE-2025-21036
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper access control in Samsung Notes prior to version 4.4.30.63 allows local privileged attackers to access exported note files. User interaction is required for triggering this vulnerability.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSamsung Notes versions prior to 4.4.30.63 contain improper access control that allows local privileged attackers to read exported note files. The vulnerability requires user interaction to trigger the export action, after which the exported files can be accessed by privileged local attackers due to insufficient permission controls.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Samsung Notes app versionGo to Settings > Apps > Samsung Notes > App info, or look in the app's About section, to find the installed version numberAffected if Version is lower than 4.4.30.63
-
Identify exported note filesSearch the device storage for files created by Samsung Notes export feature, typically found in the Downloads folder or Samsung Notes export directory with extensions like .sgx, .pdf, or .txtAffected if Any exported note files exist on the device
-
Verify file permissions on exported filesUse a file manager app or run 'ls -la' via ADB shell on the exported files to check if other apps or users have read access to the exported note filesAffected if Files have overly permissive access rights visible to privileged local attackers
-
Check for recent export activityReview the device logs or the Samsung Notes app history to identify if any notes were exported, as exploitation requires the user to trigger an export action firstAffected if Notes have been exported after the app was installed
A user is affected if Samsung Notes version is below 4.4.30.63 AND any notes have been exported, as the exported files can be read by local privileged attackers due to insufficient permission controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.4.30.63
Update Samsung Notes to version 4.4.30.63 or later to obtain the vendor patch. Until then, avoid exporting sensitive notes and consider revoking unnecessary device privileges.
4.4.30.63 or later
- Open the Samsung Notes application on your device
- Navigate to the app settings or access the Galaxy Store/Play Store
- Check for available updates and install Samsung Notes version 4.4.30.63 or later
- Verify the updated version in the app settings after the update completes
