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 confidenceThis is a missing authentication vulnerability in Samsung's Galaxy Themes Service that allows local attackers to delete arbitrary non-preloaded applications without any authentication. The issue stems from the themes service exposing an unprotected interface for application removal that lacks proper 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.
-
Identify device manufacturerCheck if the device is a Samsung Android device by going to Settings > About Phone > Manufacturer or ModelAffected if Device is not made by Samsung - not affected
-
Check Android versionNavigate to Settings > About Phone > Android Version. Confirm if the version is 11.0, 12.0, or 13.0Affected if Android version is 11.0, 12.0, or 13.0 - potentially affected
-
Verify Galaxy Themes Service presenceCheck if the Galaxy Themes app is installed by going to Settings > Apps and searching for 'Themes' or 'Galaxy Themes'Affected if Galaxy Themes Service is not installed - not affected (but unlikely on Samsung devices)
-
Check security patch levelGo to Settings > About Phone > Security Patch Level and verify the date. The fix is in SMR Jul-2023 Release 1 or laterAffected if Security Patch Level is before July 2023 - likely affected; if July 2023 or later, likely not affected
A Samsung Android device running version 11.0, 12.0, or 13.0 with a security patch level before July 2023 is likely affected by this authentication bypass in the Galaxy Themes Service.

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 · scopedApply the SMR Jul-2023 Release 1 or later security patch which addresses the authentication bypass in the Galaxy Themes Service. Until the patch is applied, limit physical access to the device and disable any theme-related services if possible.
SMR Jul-2023 Release 1
- Open Settings on the Samsung Galaxy device
- Navigate to Software update
- Tap Download and install to check for and install the latest Samsung security update
- Verify the installed SMR version is July 2023 Release 1 or later in Settings > About phone > Software information
