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 the Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if The version is 11.0, 12.0, or 13.0 specifically (not 14 or later)
-
Check the Samsung Security Maintenance Package (SMR) patch levelGo to Settings > About Phone > Software information > Build number, or run 'getprop ro.build.version.sem' via ADB. The SMR patch level format is typically SMR-XXX-YY (e.g., SMR-Jul-2023-R1)Affected if The SMR patch level is earlier than SMR-Jul-2023-R1 (e.g., SMR-Jun-2023-R1 or older)
-
Verify the EnhancedAttestationResult component presenceCheck if the EnhancedAttestationResult service exists on the device by running 'dumpsys -l | grep -i attestation' or inspecting /system/framework/ via ADBAffected if The EnhancedAttestationResult component exists and the device is on an affected Android version with pre-Jul-2023 SMR
The device is affected if it runs Android 11.0, 12.0, or 13.0 and has an SMR patch level earlier than July-2023 Release 1.
