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.
-
Find installed version of Lenovo System Interface FoundationOpen Windows Registry Editor and navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ or check the program folder in Program Files for a Lenovo folder containing System Interface Foundation files.

-
Locate the LenovoAppScenarioPluginSystem componentSearch for the file LenovoAppScenarioPluginSystem.dll in the Lenovo System Interface Foundation installation directory, typically found under C:\Program Files\Lenovo\System Interface\ or C:\Program Files (x86)\Lenovo\System Interface\.Affected if The LenovoAppScenarioPluginSystem.dll file exists in the application directory.
-
Verify the DLL loading directory is writableCheck the permissions on the Lenovo System Interface Foundation installation folder. Right-click the folder, select Properties > Security, and verify if standard users have Write or Modify permissions.Affected if The installation directory allows non-admin users to write files, enabling DLL hijacking.
