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
Buffer overflow for some Intel(R) QAT Windows software before version 2.6.0. within Ring 3: User Applications may allow a denial of service. System software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

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 · high confidence

A buffer overflow vulnerability exists in Intel QAT Windows software versions prior to 2.6.0 within user-mode (Ring 3) applications. The flaw can be exploited by an authenticated user with local access through a low-complexity attack requiring no user interaction, potentially causing denial of service by impacting system availability.

MitigationUpgrade Intel QAT Windows software to version 2.6.0 or later to remediate the buffer overflow vulnerability.

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. Locate Intel QAT installation
    Open Windows Control Panel > Programs and Features, or run 'Get-WmiObject Win32_Product | Where-Object {$_.Name -like "*QuickAssist*"}' to list installed Intel QAT software and its version
    Affected if Intel QAT software is installed with a version number lower than 2.6.0-0018
  2. Check QAT driver version
    Open Device Manager, expand 'System devices' or 'Cryptographic devices', look for 'Intel(R) QuickAssist' device, right-click and select Properties > Driver tab to view driver version
    Affected if The driver version shown is earlier than 2.6.0-0018 (note: driver version may differ from software version)
  3. Verify QAT service presence
    Open Services console (services.msc) and look for 'Intel QAT Service' or similar QAT-related service, or run 'Get-Service | Where-Object {$_.DisplayName -like "*QAT*"}'
    Affected if A QAT service exists, indicating the vulnerable software component is present in the system
  4. Compare installed version to affected range
    Document the exact version string found in Steps 1-2 and compare numerically: any version < 2.6.0-0018 (including 2.5.x, 2.0.x, 1.x, etc.) falls within the affected range
    Affected if The installed version string begins with a number lower than 2.6.0, or starts with 2.6.0 but is earlier than 2.6.0-0018

The environment is affected if Intel QAT software version is present and is less than 2.6.0-0018, as only versions prior to this release contain the vulnerable user-mode buffer overflow code.
