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 v3.2.2 and prior versions allow a local attacker get sensitive buffer information through use of uninitialized resource.

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 local attacker can exploit uninitialized resource usage in OpenHarmony v3.2.2 and prior versions to obtain sensitive buffer information, potentially exposing memory contents that were not properly cleared before use.

MitigationImplement proper initialization of all buffers and resources in the affected component to prevent information disclosure through uninitialized memory access.

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.harmonyos' or check /system/etc/version.ini for the HarmonyOS version number
    Affected if The installed version is 3.2.2 or any version prior to it (e.g., 3.2.1, 3.2.0, earlier releases)
  2. Verify the vulnerable component is present
    Locate the binary or library containing the affected component (typically in /system/lib64/ or /system/bin/) - exact filename would be determined by vendor disclosure
    Affected if The specific component handling buffer operations exists in the system image
  3. Check if affected service is running
    Use 'ps -A' or 'hdc shell ps -A' to list running processes and identify if the service utilizing the vulnerable code path is active
    Affected if The service that exercises the uninitialized buffer code path is currently running
  4. Inspect memory allocation configuration
    Review any configuration files in /etc/ or /system/etc/ that control memory initialization behavior for the affected subsystem
    Affected if Buffer initialization is disabled or set to a mode that permits uninitialized memory access

A system is affected if it runs any version of OpenHarmony at or below 3.2.2 and contains the vulnerable component with the uninitialized resource usage flaw enabled and operational.
