CVE-2026-24282
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 · uneditedOut-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 confidenceAn 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.
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 checksWork through these to decide whether this CVE applies to you.
-
Check Windows version numberRun 'winver' from the Run dialog or execute 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' in Command PromptAffected 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
-
Confirm exact OS build numberRun 'winver' or go to Settings > System > About to view the exact Build number displayedAffected if The build number is lower than the threshold for your specific Windows release (1607, 1809, 21h2, 22h2, 23h2, 24h2, 25h2, or 26h1)
-
Identify the Push Message Routing ServiceOpen 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 PowerShellAffected if The Push Message Routing Service is present and running on the system (vulnerability requires this component to be accessible)
-
Verify authenticated local access capabilityReview local user accounts and permissions on the system using 'net user' in Command Prompt or check Group Policy settings under Local Policies > Security OptionsAffected 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.
