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
An issue in the component RTKVHD64.sys of Realtek Semiconductor Corp Realtek(r) High Definition Audio Function Driver v6.0.9549.1 allows attackers to escalate privileges and execute arbitrary code via sending crafted IOCTL requests.

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 confidence

A privilege escalation vulnerability exists in the Realtek High Definition Audio Function Driver (RTKVHD64.sys) version 6.0.9549.1. The driver fails to properly validate input when handling IOCTL (I/O Control) requests, allowing a local attacker to send crafted requests and execute arbitrary code with elevated (kernel) privileges.

MitigationApply the vendor-supplied patch or update Realtek High Definition Audio Driver to a version beyond 6.0.9549.1. If the driver is unnecessary, consider removing it to reduce the attack surface.

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 the Realtek audio driver file
    Search for RTKVHD64.sys on the system using PowerShell command: Get-ChildItem -Path C:\Windows\System32\drivers -Recurse -Filter RTKVHD64.sys -ErrorAction SilentlyContinue | Select-Object FullName
    Affected if The file RTKVHD64.sys is found in the drivers directory
  2. Retrieve the driver file version
    Right-click the RTKVHD64.sys file, select Properties, then go to the Details tab to view the Product Version and File Version fields. Alternatively, use PowerShell: (Get-Item 'C:\Windows\System32\drivers\RTKVHD64.sys').VersionInfo | Select-Object ProductVersion, FileVersion
    Affected if The version displayed is 6.0.9549.1 exactly
  3. Query the installed driver version via command line
    Open Command Prompt or PowerShell and run: driverquery /v | Select-String -Pattern 'RTKVHD64' or use: Get-WmiObject Win32_PnPSignedDriver | Where-Object {$_.DeviceName -like '*Realtek*'} | Select-Object DeviceName, DriverVersion
    Affected if The driver is listed and shows version 6.0.9549.1
  4. Verify the driver is loaded and accessible
    Check if the driver is currently loaded by running: sc query RTKVHD64 or checking the device manager for Realtek High Definition Audio under Sound, video and game controllers
    Affected if The driver service exists and is in a running or stopped state, meaning the driver is installed and available for IOCTL communication

A user is affected if RTKVHD64.sys is present on the system with version 6.0.9549.1 and the driver is installed and accessible for IOCTL requests.
