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 arbitrary code execution in pre-installed apps through use after free.

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

Use-after-free vulnerability in OpenHarmony v4.0.0 and prior allows a local attacker to achieve arbitrary code execution in pre-installed applications by exploiting improper memory deallocation where a pointer to freed memory is still accessed.

MitigationApply vendor patches for OpenHarmony when available; if no patch exists, consider updating to a newer OpenHarmony version that addresses this vulnerability.

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
    Check the installed OpenHarmony version on the device or system. This may be found in system settings, about phone/device info, or by running version detection commands specific to the OpenHarmony build.
    Affected if The installed version is 4.0.0 or any version prior to 4.0.0 (e.g., 3.x, 2.x releases)
  2. Confirm pre-installed applications exist
    Inventory or list pre-installed applications on the OpenHarmony device. These are applications bundled with the system image rather than user-installed apps.
    Affected if Pre-installed applications are present on the system
  3. Identify memory management in pre-installed app code
    Analyze the binaries or source code of pre-installed applications for use-after-free patterns, specifically looking for code paths where pointers are accessed after the associated memory has been freed.
    Affected if Code in pre-installed applications contains use-after-free vulnerabilities where freed memory pointers are still accessed
  4. Check for vulnerable memory deallocation patterns
    Review the memory allocation/deallocation logic in pre-installed applications, focusing on cases where memory is freed but pointers to that memory are not nullified and are subsequently used.
    Affected if The code exhibits improper memory deallocation where freed memory pointers remain in use

A system is affected if it runs OpenHarmony version 4.0.0 or prior and contains pre-installed applications with the described use-after-free vulnerability in their memory handling logic.
