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 · unedited
A DLL hijack vulnerability was reported in Lenovo Emulator that could allow a local attacker to execute code with elevated privileges.

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 confidence

A DLL hijack vulnerability in Lenovo Emulator allows a local attacker to execute code with elevated privileges by placing a malicious DLL in a location where the application loads DLLs from insecure search paths.

MitigationRemediate by removing insecure DLL search paths from the application configuration, using absolute paths for DLL loading, or implementing digital signature verification for all loaded DLLs.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check if Lenovo Emulator is installed
    Look for Lenovo Emulator in the list of installed programs (Control Panel > Programs and Features, or run 'Get-WmiObject -Class Win32_Product' in PowerShell)
    Affected if Lenovo Emulator is present on the system
  2. Determine installed Lenovo Emulator version
    Open Lenovo Emulator and navigate to Help > About, or check the version in Add/Remove Programs. Compare the version number to 9.1.6
    Affected if The installed version is less than 9.1.6
  3. Identify DLL loading configuration
    Examine the Lenovo Emulator installation directory for configuration files (such as .ini, .cfg, or .xml files) that specify DLL search paths or loading behavior
    Affected if Configuration files reference relative paths or insecure directories for DLL loading
  4. Check for insecure DLL search paths in use
    Use Process Monitor or similar tooling to observe DLL search paths when Lenovo Emulator loads. Look for paths that permit user-controlled locations (such as the application directory, TEMP, or current working directory)
    Affected if The application loads DLLs from directories writable by non-privileged users
  5. Verify DLL file integrity controls
    Inspect the application's configuration or runtime settings to determine if digital signature verification or secure path validation is enabled for DLL loading
    Affected if No DLL integrity verification is configured and the version is below 9.1.6

A user is affected if Lenovo Emulator version is below 9.1.6 AND the application loads DLLs from insecure search paths accessible to local attackers.

Upgrade available Upgrade to 9.1.6 or later
Fixed in 9.1.6
Interim mitigation

Remediate by removing insecure DLL search paths from the application configuration, using absolute paths for DLL loading, or implementing digital signature verification for all loaded DLLs.

Recommended fix High confidence

9.1.6 or later

  1. Open Lenovo Emulator and navigate to Help > About to check the current version number
  2. Visit Lenovo's official support website (iknow.lenovo.com.cn) or the Lenovo Vantage application
  3. Locate and download Lenovo Emulator version 9.1.6 or later
  4. Close any running instances of Lenovo Emulator
  5. Run the installer and follow the on-screen prompts to complete the upgrade
  6. Restart Lenovo Emulator after installation completes
  7. Verify the version has been updated to 9.1.6 or higher via Help > About
Caveat Minor version upgrades typically retain existing configurations; backup emulator settings as precaution
