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 v4.1.0 and prior versions allow a local attacker cause crash through integer overflow.

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

Integer overflow vulnerability in OpenHarmony v4.1.0 and prior versions allows a local attacker to trigger a crash through improper integer arithmetic, resulting in denial of service.

MitigationApply patches or updates to OpenHarmony v4.1.0 when available; review and harden integer handling in affected system components to prevent overflow conditions.

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 installed OpenHarmony version
    Run 'swmgr version' or check system information panel for OpenHarmony version number
    Affected if Version number is 4.0.x or 4.1.x (any patch level)
  2. Confirm version is within affected range
    Compare installed version against the vulnerable range: >= 4.0 and <= 4.1
    Affected if Version falls within 4.0 to 4.1 inclusive
  3. Locate system components with integer operations
    Review running processes and services on the OpenHarmony device; identify components that perform arithmetic operations on untrusted input
    Affected if Integer arithmetic components are present and processing external or user-provided data
  4. Check for crash or denial of service indicators
    Review system logs (dmesg, crash dumps, fault logs) for unexpected process terminations or integer overflow error messages
    Affected if Recent crashes or process failures match the DoS pattern described in the CVE
  5. Audit component configuration
    Examine configuration files for enabled modules that handle numeric data, buffers, or memory allocation parameters
    Affected if Vulnerable integer handling code paths are enabled and accessible to local users

The environment is affected if OpenHarmony version is 4.0.x or 4.1.x and the system contains components with integer arithmetic operations accessible to local attackers.
