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 information leak 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 an out-of-bounds read vulnerability that allows a local attacker to read sensitive information from memory beyond intended buffer boundaries. This information disclosure flaw stems from improper bounds checking in affected components.

MitigationApply available security patches for OpenHarmony. If no patch is available, identify and remediate the vulnerable code path through source code review and add proper bounds validation.

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. Check OpenHarmony version
    Run 'cat /etc/version' or 'hcctl version' or check system info to retrieve the installed OpenHarmony version number
    Affected if The version is 4.0 or 4.0.1 (exact match)
  2. Confirm build date or patch level
    Check the system build information via 'getprop ro.build.version.sdk' or similar command to see if it matches the affected release dates
    Affected if Build corresponds to unpatched 4.0 or 4.0.1 releases
  3. Identify affected component in use
    Review application or service logs for the component that handles memory operations or buffer processing, as the flaw stems from improper bounds checking
    Affected if A component performing buffer operations without proper bounds validation is active

The environment is affected if OpenHarmony version is exactly 4.0 or 4.0.1 and the vulnerable component with the bounds-checking flaw is in use.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
