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
Out-of-bounds read in Push Message Routing Service 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

An out-of-bounds read vulnerability exists in the Push Message Routing Service where improper bounds validation during memory access allows an authenticated local attacker to read adjacent memory contents, potentially exposing sensitive information.

MitigationApply vendor-provided security patches for the Push Message Routing Service and implement proper bounds checking in memory access operations.

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

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 number
    Run 'winver' from the Run dialog or execute 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' in Command Prompt
    Affected if The displayed version falls within any of the following ranges: 10.0.14393.x before 8957, 10.0.17763.x before 8511, 10.0.19044.x before 7058, 10.0.19045.x before 7058, 10.0.22631.x before 6783, 10.0.26100.x before 7979, 10.0.26200.x before 7979, or 10.0.28000.x before 1719
  2. Confirm exact OS build number
    Run 'winver' or go to Settings > System > About to view the exact Build number displayed
    Affected if The build number is lower than the threshold for your specific Windows release (1607, 1809, 21h2, 22h2, 23h2, 24h2, 25h2, or 26h1)
  3. Identify the Push Message Routing Service
    Open Services console (services.msc) and look for a service related to Push Message Routing or Push Messaging, or run 'get-service | where-object {$_.DisplayName -like "*push*"}' in PowerShell
    Affected if The Push Message Routing Service is present and running on the system (vulnerability requires this component to be accessible)
  4. Verify authenticated local access capability
    Review local user accounts and permissions on the system using 'net user' in Command Prompt or check Group Policy settings under Local Policies > Security Options
    Affected if The system allows authenticated local user accounts (standard configuration for most Windows installations)

Your system is affected if it runs any of the listed Windows 10 or Windows 11 versions with a build number lower than the threshold AND the Push Message Routing Service is present and accessible to authenticated local users.

Upgrade to Windows 10 build 10.0.14393.8957 or later for 1607; 10.0.17763.8511 or later for 1809; 10.0.19044.7058 or later for 21h2; 10.0.19045.7058 or later for 22h2; Windows 11 build 10.0.22631.6783 or later for 23h2; 10.0.26100.7979 or later for 24h2; 10.0.26200.7979 or later for 25h2; 10.0.28000

  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. Alternatively, manually download and install the specific cumulative update for your Windows version that includes build 10.0.14393.8957 (Windows 10 1607), 10.0.17763.8511 (Windows 10 1809), 10.0.19044.7058 (Windows 10 21h2), 10.0.19045.7058 (Windows 10 22h2), 10.0.22631.6783 (Windows 11 23h2), 10.0.26100.7979 (Windows 11 24h2), 10.0.26200.7979 (Windows 11 25h2), or 10.0.28000.1719 (Windows 11 26h
  4. Restart the system after updates are installed to ensure the Push Message Routing Service patch is fully applied
  5. Verify the installed build number by running 'winver' command to confirm the fix is in place
