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
Improper access control in some Intel(R) Thunderbolt(TM) DCH drivers for Windows before version 88 may allow an authenticated user to potentially enable denial of service 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. Verify Intel Thunderbolt DCH driver is installed
    Open Device Manager, expand the 'System devices' category, and look for an entry named 'Intel(R) Thunderbolt(TM) Controller' or similar Intel Thunderbolt driver entry.
    Affected if No Intel Thunderbolt driver is found in Device Manager, then the system is not affected by this specific vulnerability.
  2. Obtain the installed Thunderbolt driver version
    Right-click the Intel Thunderbolt driver entry in Device Manager, select 'Properties', go to the 'Driver' tab, and note the 'Driver Version' field.
    Affected if The driver version shown is a version number lower than 88 (for example, 1.41.654.0 or 87.x.x.x), indicating the system is vulnerable.
  3. Confirm driver vendor is Intel
    In the same Driver tab within Device Manager, verify the 'Driver Provider' or 'Driver Vendor' field shows Intel Corporation as the provider.
    Affected if The driver is present but from a different vendor, the specific CVE may not apply to that implementation.
  4. Check for driver file version as secondary confirmation
    In the Driver tab, click 'Driver Details' and review the listed .sys files associated with the Thunderbolt driver. Note any version numbers displayed.
    Affected if The file versions shown correspond to versions below 88, confirming the vulnerability is present.

The system is affected if the Intel Thunderbolt DCH driver for Windows is installed and its version number is lower than 88.

Interim mitigation

Update Intel Thunderbolt DCH drivers for Windows to version 88 or later to remediate this vulnerability.

Recommended fix Moderate confidence

Intel Thunderbolt DCH Driver for Windows version 88 or later

  1. Identify the current Thunderbolt DCH driver version by opening Device Manager, expanding the 'System devices' or 'Universal Serial Bus controllers' category, right-clicking on the Thunderbolt device, selecting 'Properties', and viewing the Driver version under the Driver tab.
  2. Visit the official Intel Support website and search for Thunderbolt DCH driver downloads for Windows.
  3. Download the latest Thunderbolt DCH driver version 88 or later for your specific Windows version.
  4. Run the downloaded installer and follow the on-screen prompts to install the updated driver.
  5. Restart the computer when prompted to complete the installation.
  6. Verify the new driver version is installed by checking Device Manager again to confirm version 88 or higher is now in use.
