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
Version update determination vulnerability in the user profile module.Successful exploitation of this vulnerability may cause repeated HMS Core updates and cause services to fail.

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 logic vulnerability in the version update determination mechanism of the HMS Core user profile module allows an attacker to cause the system to incorrectly determine that updates are needed, resulting in repeated HMS Core update attempts that can disrupt services.

MitigationApply the vendor-provided patch for HMS Core when available; until then, monitor for unusual update behavior and consider implementing application-level mitigations to handle repeated update failures gracefully.

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. Verify Emui version
    Check device settings: Settings > About Phone > Version, or run 'getprop ro.build.version.emui' via ADB shell to confirm the installed Emui version is exactly 13.0.0
    Affected if The device is running Emui version 13.0.0 specifically
  2. Confirm HMS Core presence
    Check if HMS Core is installed on the device via Settings > Apps > HMS Core, or list installed packages using 'pm list packages | grep huawei' via ADB shell
    Affected if HMS Core application is installed on the device
  3. Monitor for repeated update attempts
    Check HMS Core app logs via 'logcat -d | grep -i update' via ADB shell, or observe if the HMS Core update notification appears repeatedly within a short time period
    Affected if The system repeatedly prompts for HMS Core updates or generates update-related error logs in rapid succession
  4. Inspect user profile module behavior
    Within HMS Core, navigate to Settings > User Profile or Profile settings, and observe if the app triggers unnecessary update checks when accessing or modifying profile information
    Affected if Accessing or modifying user profile data triggers unexpected or repeated update check attempts

A device is affected if it runs Emui 13.0.0 with HMS Core installed and exhibits repeated, unnecessary HMS Core update attempts triggered by the user profile module.
