CVE-2025-12046
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA DLL hijacking vulnerability was reported in the Lenovo App Store and Lenovo Browser applications that could allow a local authenticated user to execute code with elevated privileges under certain conditions.
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 DLL hijacking vulnerability in Lenovo App Store and Lenovo Browser applications where a local authenticated user can place a malicious DLL in a location that the vulnerable application loads from, achieving code execution with elevated privileges.

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 installed Lenovo applicationsCheck for Lenovo App Store and Lenovo Browser installations. On Windows, inspect common installation paths such as C:\Program Files\Lenovo\App Store or C:\Program Files\Lenovo\LenovoBrowser. Use PowerShell command: Get-ChildItem 'C:\Program Files\Lenovo' -ErrorAction SilentlyContinue | Select-Object NameAffected if Lenovo App Store or Lenovo Browser is installed on the system
-
Locate application executable directoriesFind the installation directories of Lenovo App Store and Lenovo Browser. Typical locations include C:\Program Files\Lenovo\App Store\ and C:\Program Files\Lenovo\LenovoBrowser\. Right-click the shortcuts for these applications and select 'Open file location' to confirm pathsAffected if The application binaries are located in directories with weak permissions
-
Enumerate DLL files in application directoriesList all DLL files in the Lenovo App Store and Lenovo Browser installation directories. Use command: Get-ChildItem 'C:\Program Files\Lenovo\App Store\' -Filter *.dll -Recurse -ErrorAction SilentlyContinue | Select-Object FullName, LastWriteTimeAffected if Unexpected or recently modified DLL files are present that were not shipped with the application
-
Check write permissions on application directoriesReview ACL permissions on the Lenovo App Store and Lenovo Browser directories. Use icacls command: icacls 'C:\Program Files\Lenovo\App Store' or check via Security tab in folder Properties. Verify that standard users do not have Write or Modify permissions to these directoriesAffected if Non-administrative users have Write or Modify access to application directories, allowing DLL injection
-
Monitor for DLL search order hijacking opportunitiesIdentify if application directories are present in system PATH or are loaded before system directories. Check application manifest or use Process Monitor (Sysinternals) to observe DLL load behavior when launching the applicationsAffected if The vulnerable application loads DLLs from directories with weak permissions before system directories
A user is affected if Lenovo App Store or Lenovo Browser is installed and the application directories allow standard users to write files, enabling DLL hijacking injection.

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.
From vendor dataApply vendor patches from Lenovo when available. Until then, restrict write access to application directories and monitor for suspicious DLL files in those locations.
