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
Insertion of sensitive information into log file in Windows Kernel allows an authorized attacker to disclose information locally.

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

Windows Kernel vulnerability where sensitive information is inadvertently written to log files, enabling a locally authorized attacker to read and disclose that information. The flaw involves improper handling of data before logging operations in the kernel.

MitigationApply Microsoft security updates for Windows Kernel when available. Restrict access to system log files to minimize exposure of any sensitive data that may be written.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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. Check Windows build version
    Open Command Prompt or PowerShell and run 'winver' or 'systeminfo | findstr /B /C:"OS Version"' to obtain the full build number
    Affected if The build number falls below the fixed version for your specific Windows release (e.g., below 10.0.14393.9060 for Windows 10 1607, below 10.0.17763.8644 for Windows 10 1809, etc.)
  2. Identify Windows release version
    Run 'winver' to see the Windows release name (such as 1607, 1809, 21h2, 22h2, 23h2, 24h2, 25h2, or 26h1)
    Affected if The release matches any of the affected versions listed and the build number is below the corresponding threshold
  3. Verify kernel version
    Run 'ver' at command prompt or check the file properties of ntoskrnl.exe in C:\Windows\System32
    Affected if The kernel version corresponds to an affected Windows build
  4. Review Windows event logs for sensitive data
    Open Event Viewer and examine Windows Logs (System, Security, Application) and any custom application logs for unexpected sensitive information such as credentials, tokens, or private data
    Affected if Log entries contain sensitive information that should not have been written to logs

You are affected if your Windows build number is below the fixed version for your specific Windows release (1607, 1809, 21h2, 22h2, 23h2, 24h2, 25h2, or 26h1) as listed in the affected versions.

Recommended fix High confidence

Windows 10 1607: 10.0.14393.9060 | Windows 10 1809: 10.0.17763.8644 | Windows 10 21h2: 10.0.19044.7184 | Windows 10 22h2: 10.0.19045.7184 | Windows 11 23h2: 10.0.22631.6936 | Windows 11 24h2: 10.0.26100.8246 | Windows 11 25h2: 10.0.26200.8246 | Windows 11 26h1: 10.0.28000.1836

  1. Open Windows Settings and navigate to Update & Security > Windows Update
  2. Click 'Check for updates' to download and install the latest security updates
  3. After installation, verify the kernel version matches or exceeds the fixed version for your Windows release
  4. Alternatively, manually install the specific KB security update from Microsoft Update Catalog corresponding to your Windows version
  5. Restart the system to complete the patch installation
  6. Confirm the update was applied by checking Windows Update history for the relevant security patch
Caveat Standard Windows security update - minimal risk; ensure backups and test in non-production first
