CVE-2023-41252
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 · uneditedOut-of-bounds read in some Intel(R) QAT software drivers for Windows before version QAT1.7-W-1.11.0 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.
dbcve analysis · high confidenceOut-of-bounds read vulnerability in Intel QAT (QuickAssist Technology) software drivers for Windows. This driver-level flaw allows an authenticated local user to potentially trigger a denial of service condition by reading memory outside allocated buffer boundaries, possibly causing a crash or hang.

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.
-
Check if Intel QAT driver service existsOpen Services (services.msc) and look for a service related to Intel QuickAssist Technology, or run 'sc query type= driver' in Command Prompt and search for QAT-related entriesAffected if An Intel QAT driver service is present on the system
-
Retrieve the installed driver versionIn Device Manager, expand the relevant Intel QAT driver node, right-click and select Properties, then go to the Driver tab. Alternatively, right-click the driver file in the installation directory and select Properties > Details to view the File VersionAffected if The driver version shown is earlier than 1.11.0 (for example, 1.10.x, 1.9.x, or any version number below 1.11.0)
-
Check driver file version via PowerShellRun Get-ChildItem -Path 'C:\Program Files\Intel\QAT' -Recurse -Filter '*.sys' | Select-Object Name, VersionInfo to list driver files and their versions if the QAT software was installed to the default directoryAffected if Any QAT driver file (.sys) shows a version property lower than 1.11.0.0
A user is affected if the Intel QAT driver is installed and its version is below 1.11.0, as only versions prior to 1.11.0 contain the out-of-bounds read vulnerability.

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.
dbcve · scoped1.11.0
Update Intel QAT software drivers for Windows to version QAT1.7-W-1.11.0 or later. Organizations using Intel QAT acceleration hardware should prioritize patching due to the driver being a kernel-level component.
QAT1.7-W-1.11.0
- Identify current QAT driver version installed on the Windows system via Device Manager or QAT diagnostic tools
- Download the Intel QuickAssist Technology Driver version QAT1.7-W-1.11.0 or later from the official Intel website
- Stop any services or applications that utilize the QAT driver
- Uninstall the current QAT driver through Windows Device Manager or the provided uninstaller
- Install the updated QAT1.7-W-1.11.0 driver package following Intel's installation documentation
- Restart the system to ensure the new driver loads properly
- Verify the installed driver version matches QAT1.7-W-1.11.0 or later
