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 remote attacker arbitrary code execution in pre-installed apps through out-of-bounds write.

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 write vulnerability in pre-installed applications that can be exploited by a remote attacker to achieve arbitrary code execution. The vulnerability stems from improper bounds checking when writing to memory, allowing an attacker to overwrite adjacent memory locations and hijack control flow.

MitigationApply security patches from OpenHarmony project as soon as available; until then, minimize network exposure of affected devices and consider network segmentation for IoT/embedded devices running OpenHarmony.

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 installation
    Check system information or boot logs for OpenHarmony OS identity. On embedded devices, inspect /proc/version, system properties, or boot messages for 'OpenHarmony' or 'Openatom' strings.
    Affected if The system runs OpenHarmony as its operating system.
  2. Determine OpenHarmony version
    Retrieve the installed OpenHarmony version from system settings, version files, or command-line tools such as 'getprop' on Android-like builds, or by examining /etc/version or /usr/lib/version information.
    Affected if The installed version is 4.0.0 or any version prior to 4.0.0.
  3. Locate pre-installed applications
    Examine the application directory for pre-installed apps. Common locations include /system/app, /preinstall, or /vendor/preinstall on OpenHarmony-based devices. List installed packages using system package managers or application management tools.
    Affected if Pre-installed applications exist on the device and are actively used.
  4. Assess network exposure
    Review network configuration and firewall rules to determine if the device is directly accessible from untrusted networks. Check listening ports and services bound to external interfaces.
    Affected if The device or its pre-installed applications are exposed to untrusted network paths without adequate network segmentation or filtering.

A user is affected if their device runs OpenHarmony version 4.0.0 or prior, has pre-installed applications present, and those applications or the device itself are reachable from untrusted networks.
