CVE-2026-0827
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 · uneditedDuring an internal security assessment, a potential vulnerability was discovered in Lenovo Diagnostics and the HardwareScanAddin used in Lenovo Vantage that, during installation or when using hardware scan, could allow a local authenticated user to perform an arbitrary file write 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 confidenceLenovo Diagnostics and the HardwareScanAddin component in Lenovo Vantage contain a local privilege escalation vulnerability where an authenticated local user can perform arbitrary file writes with elevated (SYSTEM) privileges during installation or hardware scan operations. This could allow a local attacker to achieve code execution at elevated privilege levels.

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.
-
Confirm Lenovo Vantage installationOpen Programs and Features (appwiz.cpl) or check for Lenovo Vantage in the Start Menu, or look for the installation directory under C:\Program Files\Lenovo\Vantage or similar pathsAffected if Lenovo Vantage is not installed on the system
-
Identify Lenovo Vantage versionRight-click on Lenovo Vantage in Programs and Features to view the version, or right-click the executable and view Properties > Details, or check the version in the software's About/Help sectionAffected if The installed version has not been patched and falls within the vulnerable version range
-
Locate HardwareScanAddin componentSearch for HardwareScanAddin.dll or HardwareScanAddin in the Lenovo Vantage installation directory (typically under C:\Program Files\Lenovo\Vantage or C:\Program Files (x86)\Lenovo\Vantage)Affected if The HardwareScanAddin component is present in the installation
-
Check for recent installation or scan activityReview Windows Event Viewer logs under Application and System logs for events related to Lenovo Diagnostics or HardwareScan operations, or check recent file activity in the Lenovo Vantage installation directoryAffected if Recent installation, repair, or hardware scan operations have been performed on the system
-
Verify local user accessCheck if standard (non-admin) local users have access to run Lenovo Vantage or Diagnostics tools, or check group membership for users who can access Lenovo Vantage functionalityAffected if Standard local users can access and execute Lenovo Vantage or Diagnostics features
A user is affected if Lenovo Vantage with the HardwareScanAddin component is installed, the version is within the vulnerable range, and local non-privileged users have access to run the software.

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-supplied patches from Lenovo when available. Until then, restrict local user access to Lenovo Vantage/Diagnostics functionality and monitor for suspicious file activity in system directories.
