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 and note the displayed version numberAffected if Android version is 11.0, 12.0, or 13.0
-
Check Samsung SMR release versionGo to Settings > About Phone > Software information and look for the SMR (Samsung Mobile Release) fieldAffected if SMR version is earlier than Jul-2023 Release 1 or the SMR field is not visible
-
Verify LSOItemData component presenceInspect installed Samsung applications that contain LSOItemData functionality; this component is part of Samsung's proprietary software layerAffected if LSOItemData component is present on the device and the version checks in steps 1-2 indicate an affected combination
The device is affected if it runs Android 11.0, 12.0, or 13.0 with a Samsung SMR version prior to Jul-2023 Release 1, as this combination falls within the vulnerable version range for the LSOItemData input validation flaw.
