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
in OpenHarmony v5.1.0 and prior versions allow a local attacker cause DOS through improper input.

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

This is a local denial-of-service vulnerability in OpenHarmony v5.1.0 and prior versions. A local attacker can cause the system or a component to become unavailable by providing improper input, likely triggering a crash, hang, or resource exhaustion due to missing or insufficient input validation.

MitigationUpgrade to a patched version of OpenHarmony beyond v5.1.0. If upgrading is not immediately feasible, restrict local access to trusted users only and monitor for service disruptions.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify OpenHarmony version
    Run 'getprop ro.build.version.sdk' or check /system/etc/version.ini to determine the installed OpenHarmony version
    Affected if Version is 5.0.3 or 5.1.0 (or any version prior to 5.1.0)
  2. Determine if component input validation is in use
    Review application or system component logs in /var/log/ for error messages indicating input validation failures, crashes, or resource exhaustion related to user-provided data
    Affected if Components handling external input are experiencing crashes, hangs, or unexpected termination
  3. Verify local access controls
    Check user permissions and process isolation settings using 'ls -la /proc/' and review which local users have access to sensitive system components
    Affected if Untrusted local users have access to components that process input without proper validation
  4. Monitor for denial-of-service symptoms
    Review system logs (dmesg, logcat) for repeated process crashes, hung tasks, or abnormal resource consumption patterns in affected components
    Affected if System or specific components are becoming unavailable, crashing repeatedly, or exhibiting resource exhaustion without other explanation

A user is affected if they are running OpenHarmony version 5.0.3 or 5.1.0 (or any version prior to 5.1.0) and experiencing unexplained component crashes, hangs, or service unavailability triggered by local input handling.
