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
Insecure inherited permissions in the installer for the Intel(R) NUC M15 Laptop Kit audio driver pack before version 1.3 may allow an authenticated user to potentially enable escalation of privilege via local access.

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.

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. Confirm system is an Intel NUC M15 Laptop Kit
    Check system information or product model through system information utility (msinfo32) or by inspecting the system BIOS/UEFI for the model designation
    Affected if System model is Intel NUC M15 Laptop Kit
  2. Identify the installed audio driver pack version
    Open Programs and Features in Control Panel or use 'Get-WmiObject -Class Win32_Product' to list installed software, then locate the Intel NUC M15 Audio Driver Pack entry and note its version
    Affected if Audio driver pack version is present but less than 1.3
  3. Locate the audio driver installation directory
    Check the default installation path typically under C:\Program Files\Intel\ or C:\Program Files (x86)\Intel\ for the NUC audio driver pack folder, or right-click the installed program in Programs and Features and select Properties to view the installation location
    Affected if Installation directory exists and version is below 1.3
  4. Verify permissions on the installation directory
    Right-click the audio driver installation folder, select Properties, then Security tab. Check if Authenticated Users or standard users have Full Control, Modify, or Write permissions on the folder
    Affected if Authenticated local users have elevated permissions (Write, Modify, or Full Control) on the driver pack installation folder

System is affected if it is an Intel NUC M15 Laptop Kit with Intel NUC M15 Audio Driver Pack installed at a version lower than 1.3 and the installation directory grants excessive permissions to authenticated users.
