CVE-2026-21015
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 permissions in FactoryCamera prior to SMR May-2026 Release 1 allows local attacker to access unique identifier.
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 FactoryCamera application in Samsung mobile devices had incorrect default file system permissions prior to the SMR May-2026 Release 1. This allowed any local application or user with local device access to read a unique identifier (likely a device-specific serial number or camera sensor identifier) that should have been protected by proper permission controls. A local attacker would need to install a malicious app or have ADB shell access to exploit this.

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 Android versionGo to Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release'Affected if Version is 14.0, 15.0, or 16.0
-
Verify FactoryCamera application existsCheck if FactoryCamera is listed in installed apps via Settings > Apps, or run 'adb shell pm list packages | grep factorycamera'Affected if FactoryCamera is installed on an affected Android version
-
Inspect FactoryCamera data directory permissionsRun 'adb shell ls -la /data/data/com.samsung.factorycamera' or check the app's internal storage directory permissionsAffected if Directory permissions allow read access by other applications (world-readable) or ADB shell users without proper restrictions
-
Check for exposed unique identifier filesLook for files in the app's data directory that may contain device-specific serial numbers or camera sensor identifiers, such as in /data/data/com.samsung.factorycamera/shared_prefs/ or similar locationsAffected if Unique identifier files are readable by other apps or accessible via ADB shell without authentication
A user is affected if their Samsung device runs Android 14.0, 15.0, or 16.0 with FactoryCamera installed, and the app's data directory or identifier files have overly permissive access 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 · scopedUpdate affected Samsung devices to the SMR May-2026 Release 1 or later to receive the corrected default permissions. As a defensive measure, review installed applications for unnecessary permissions and avoid sideloading apps from untrusted sources.
SMR May-2026 Release 1
- Navigate to Settings > Software Update on the Samsung device
- Tap 'Download and install' to check for and install the latest security update
- Ensure the device updates to SMR May-2026 Release 1 or later which contains the corrected FactoryCamera permissions
