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
Out-of-bounds array access issue due to insufficient data verification in the location service module. Impact: Successful exploitation of this vulnerability may affect availability.

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 an out-of-bounds array access vulnerability in the location service module caused by insufficient data validation. The vulnerability allows an attacker to read or write beyond array boundaries, potentially causing a denial of service through a crash or unexpected behavior.

MitigationImplement proper bounds checking before array access operations in the location service module and add input validation to ensure all indices fall within valid array bounds.

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 HarmonyOS version
    Check the installed Huawei HarmonyOS version on the device using system settings or 'getprop' command (e.g., 'getprop ro.build.version.huawei' or 'getprop ro.build.version.release')
    Affected if The installed version is exactly 5.0.1 or exactly 5.1.0
  2. Confirm location service module is in use
    Verify the location service module is enabled or being accessed on the device. This can be done by checking system services, location permissions, or any location-based applications running
    Affected if The location service module is active, enabled, or being invoked by any application
  3. Verify vulnerable code path is reachable
    Determine whether any application or system component makes calls to the location service module that could trigger the array access operation
    Affected if The location service module processes requests or data that could reach the vulnerable array access code path

If the HarmonyOS version is exactly 5.0.1 or 5.1.0 and the location service module is enabled or actively processing location-related requests, the device is affected by this out-of-bounds array access vulnerability.
