CVE-2025-54114
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 · uneditedConcurrent execution using shared resource with improper synchronization ('race condition') in Windows Connected Devices Platform Service 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 confidenceA race condition vulnerability exists in the Windows Connected Devices Platform Service where improper synchronization of shared resources allows an authorized local attacker to elevate their privileges. The attacker exploits the timing window in the service's concurrent operations to gain higher-level system access.

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.
-
Identify Windows version and build numberRun 'winver' or 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"' from Command Prompt to obtain the exact Windows version and build numberAffected if The installed build number falls below any of these thresholds: 14393.8422 (Win10 1607/Server 2016), 19044.6332 (Win10 21h2), 19045.6332 (Win10 22h2), 22621.5909 (Win11 22h2), 22631.5909 (Win11 23h2), 26100.6508 (Win11 24h2), or 20348.4106 (Server 2022)
-
Verify Connected Devices Platform Service statusRun 'sc query cdpsvc' or open Services.msc and locate 'Connected Devices Platform Service' (Cdpsvc) to check if it is runningAffected if The service is running on an unpatched Windows version (see step 1) - the race condition exists in this service's concurrent operations
-
Check service binary versionLocate the service executable at %SystemRoot%\System32\CdSetup.dll or check the cdpsvc service binary via 'sc qc cdpsvc' and inspect the binary file version propertiesAffected if The binary version is older than the patched versions corresponding to the affected build ranges listed in step 1
-
Review service ACL and permissionsRun 'sc sdshow cdpsvc' to display the Security Descriptor Definition Language (SDDL) for the service and verify if low-privilege accounts have excessive service accessAffected if Low-privilege users have permissions to interact with the cdpsvc service in a way that could trigger the race condition (improper synchronization of shared resources)
-
Audit recent service-related eventsOpen Event Viewer and check Windows Logs\System for Event ID 7045 (new service installed) or 7036 (service state change) related to cdpsvc, and look for unexpected child processes spawned from the serviceAffected if Unexpected service changes or child process spawns indicate potential exploitation activity targeting the race condition
You are affected if your Windows build number is below the thresholds listed for your Windows version AND the Connected Devices Platform Service is running.
