CVE-2025-20910
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 · uneditedIncorrect default permission in Galaxy Watch Gallery prior to SMR Mar-2025 Release 1 allows local attackers to access data in Galaxy Watch Gallery.
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 · moderate confidenceThe Galaxy Watch Gallery application has incorrect default permissions set, allowing local attackers to access sensitive data stored in the Gallery. This permission misconfiguration enables unauthorized access to images and other media stored on the wearable device without proper authentication or authorization checks.

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.
-
Verify Galaxy Watch Wear OS versionOn the Galaxy Watch, go to Settings > About Watch > Software Version. Alternatively, check via paired phone in Samsung Galaxy Wearable app under Watch Information > Software VersionAffected if The displayed version is exactly 5.0 (Wear OS 5.0)
-
Confirm Gallery application is installedAccess the app list on the Galaxy Watch or via the paired phone's Galaxy Wearable app. Locate the Gallery or Photos applicationAffected if The Gallery application is present on the device
-
Inspect Gallery application permissionsOn Galaxy Watch: Settings > Apps > Gallery > Permissions. On paired phone: Galaxy Wearable app > Watch Apps > Gallery > PermissionsAffected if The permissions show unusually broad access (such as Storage or Media access granted by default without user confirmation, or permissions that allow other apps or local access to read Gallery content)
-
Check if device has not received SMR updateOn Galaxy Watch: Settings > About Watch > Software Version > Check for updates. Or check the last update date in Galaxy Wearable appAffected if The device remains on the original Wear OS 5.0 release and has not applied the SMR Mar-2025 Release 1 or later update
If the Galaxy Watch runs Wear OS 5.0 and has the Gallery application with default permissions that allow unauthorized media access, the device is likely affected by this vulnerability.

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 · scopedUpdate Galaxy Watch devices to SMR Mar-2025 Release 1 or later to receive the corrected default permission configuration for the Gallery application.
SMR Mar-2025 Release 1
- Check your Galaxy Watch model and ensure it is running Wear OS 5.0
- Navigate to Settings > Software update on your Galaxy Watch or paired smartphone
