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 Android versionGo to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADBAffected if Android version is 14.0 (one of the affected versions)
-
Check Samsung security patch levelGo to Settings > About Phone > Software information > Security patch level, or run 'getprop ro.security.patch' via ADBAffected if Security patch level is earlier than 2025-01-01 (SMR January-2025 Release 1)
-
Confirm Samsung deviceCheck that the device is a Samsung model by running 'getprop ro.product.brand' or checking Settings > About Phone > Device nameAffected if Device is a Samsung Android device (the vulnerability affects Samsung's implementation of NotificationManager)
-
Verify NotificationManager presenceCheck if the NotificationManager system service is available by running 'dumpsys notification' via ADB or checking Settings > Apps > System apps for NotificationManagerAffected if NotificationManager service is present (this is a core system component required for the vulnerability to apply)
