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 v4.0.0 and prior versions allow a local attacker cause DOS through out-of-bounds read.

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

OpenHarmony v4.0.0 and prior versions contain a local denial-of-service vulnerability where an attacker can trigger an out-of-bounds read, causing the system to become unstable or unavailable. The CVSS 5.5 indicates a local attack vector with only availability impact.

MitigationApply any available security patches for OpenHarmony; if no patch exists, conduct source code review to identify and fix the missing bounds checks that enable the out-of-bounds read.

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 the installed OpenHarmony version
    Run 'swmgr version' or check /etc/os-release to determine the exact version number of OpenHarmony installed on the device
    Affected if The version is 4.0.x or 4.1.x (any patch level within the 4.0 to 4.1 range)
  2. Confirm the vulnerability is locally exploitable
    Verify the device can run local applications or scripts, as this DoS requires local access rather than remote network access
    Affected if Local application execution is permitted and the attacker can run code on the system
  3. Check for available security patches
    Query the OpenHarmony update repository or vendor support channels for CVE-2024-47402 security updates
    Affected if No patch for CVE-2024-47402 has been applied to the installed version
  4. Monitor for system instability symptoms
    Review system logs (/var/log/messages or dmesg) for crashes, process terminations, or kernel panics that may indicate out-of-bounds read exploitation
    Affected if Unexplained system crashes or stability issues occur on the affected version

The environment is affected if OpenHarmony version 4.0 or 4.1 is installed and no CVE-2024-47402 security patch has been applied.
