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
Use after free in Windows Speech Brokered Api allows an authorized attacker to elevate privileges 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

A use-after-free vulnerability in the Windows Speech Brokered API allows a locally authorized attacker to exploit memory corruption and elevate privileges to higher integrity levels on the affected system.

MitigationApply Microsoft security updates for this vulnerability (once available) to all affected Windows systems. If the Speech Brokered API is not required, consider disabling the Windows Speech service as a defense-in-depth measure.

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 version against affected ranges
    Run 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' to identify the exact Windows build number, then compare against the listed version thresholds: Windows 10 1607 < 10.0.14393.9060, 1809 < 10.0.17763.8644, 21h2 < 10.0.19044.7184, 22h2 < 10.0.19045.7184; Windows 11 23h2 < 10.0.22631.6936, 24h2 < 10.0.26100.8246, 25h2 < 10.0.26200.8246, 26h1 < 10.0.28000.1836
    Affected if The installed Windows build number falls below the threshold for the corresponding version branch
  2. Verify Windows Speech service status
    Open Services (services.msc) and locate the 'Windows Speech' service or check via PowerShell: 'Get-Service -Name "Speech*"' to enumerate speech-related services
    Affected if The Windows Speech service is installed and running on the system
  3. Confirm Speech Brokered API availability
    Check for the presence of speech broker components by examining: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Brokered in the registry, or look for sapi.dll and related speech runtime files in System32
    Affected if The Speech Brokered API components are registered and accessible on the system

A system is affected if it runs a Windows version below the specified build thresholds AND has the Windows Speech service or Speech Brokered API components enabled.

Recommended fix High confidence

Upgrade to the fixed build for your Windows version: Windows 10 1607 to build 10.0.14393.9060, Windows 10 1809 to build 10.0.17763.8644, Windows 10 21h2 to build 10.0.19044.7184, Windows 10 22h2 to build 10.0.19045.7184, Windows 11 23h2 to build 10.0.22631.6936, Windows 11 24h2 to build 10.0.26100.8

  1. 1. Identify the current Windows version by running 'winver' or 'systeminfo' in Command Prompt
  2. 2. Determine which Windows 10 or Windows 11 version and build is installed
  3. 3. Navigate to Windows Update: Settings > Update & Security > Windows Update
  4. 4. Check for updates and install all available security updates
  5. 5. Alternatively, manually download the specific security update for your Windows version from the Microsoft Update Catalog (catalog.update.microsoft.com)
  6. 6. After installation, restart the system to apply the changes
  7. 7. Verify the build number matches or exceeds the fixed version for your Windows release
