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 rtkio64.sys of Realtek Semiconductor Corp Realtek lO Driver v1.008.0823.2017 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 I/O Driver (rtkio64.sys) version 1.008.0823.2017. Local attackers can send crafted IOCTL (I/O Control) requests to the kernel-mode driver to escalate privileges and execute arbitrary code with kernel-level privileges.

MitigationUpdate the Realtek I/O Driver to a patched version once available, or restrict or disable the driver if not required for system operation.

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 rtkio64.sys driver file
    Search for rtkio64.sys in the Windows System32\drivers directory using File Explorer or PowerShell: Get-ChildItem -Path C:\Windows\System32\drivers -Filter rtkio64.sys -Recurse -ErrorAction SilentlyContinue
    Affected if The driver file exists on the system
  2. Retrieve the driver file version
    Right-click rtkio64.sys, select Properties, then Details to view the File Version field, or run: (Get-Item 'C:\Windows\System32\drivers\rtkio64.sys').VersionInfo
    Affected if The version displayed is 1.008.0823.2017
  3. Check if the driver is currently loaded
    Open Command Prompt as Administrator and run: sc query rtkio64 or use PowerShell: Get-Process | Where-Object {$_.Name -like '*rtk*'}
    Affected if The driver shows as RUNNING or a process using the driver is active
  4. Compare against the affected version
    Compare your retrieved version string (for example, from the File Version field) against the known affected version 1.008.0823.2017
    Affected if Your installed version matches or is earlier than 1.008.0823.2017 and no later patched version is confirmed

If the rtkio64.sys driver is present and its version is 1.008.0823.2017 or earlier, the system is affected by this privilege escalation vulnerability.
