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 v5.0.3 and prior versions allow a local attacker case DOS through missing release of memory.

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 v5.0.3 and prior versions contain a memory leak where allocated memory is not properly released, allowing a local attacker to exhaust system resources and cause denial of service.

MitigationUpgrade to a patched version of OpenHarmony beyond v5.0.3 when available, or identify and patch the specific code path failing to release memory.

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 the command to display the system version, such as 'cat /proc/version' or 'ohosver' if available, or check the system build information in the settings
    Affected if The version displayed is 5.0.3 or any version prior to 5.0.3
  2. Check system memory usage
    Monitor system memory consumption over time using commands like 'cat /proc/meminfo' or system monitoring tools, observing for continuously increasing memory usage that does not decrease
    Affected if Memory usage steadily increases without returning to baseline levels during normal operation
  3. Identify processes with abnormal memory growth
    Use process monitoring commands such as 'ps' or '/proc/<pid>/status' to examine memory usage (VmRSS/VmSize) of running processes over an extended period
    Affected if One or more processes show continuous memory growth without stabilization or release
  4. Review system logs for resource exhaustion events
    Examine system log files in /var/log or using 'dmesg' for out-of-memory (OOM) killer events, memory allocation failures, or resource exhaustion warnings
    Affected if Logs contain OOM events, memory allocation failures, or indications of system resource exhaustion

A user is affected if their OpenHarmony installation is version 5.0.3 or prior and exhibits symptoms of memory exhaustion such as continuously growing process memory usage or OOM events.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

dbcve · scoped
Upgrade available Upgrade to a release after 5.0.3
Interim mitigation

Upgrade to a patched version of OpenHarmony beyond v5.0.3 when available, or identify and patch the specific code path failing to release memory.

Recommended fix Moderate confidence

OpenHarmony 5.0.4 or later (verify release notes on gitee.com for exact version containing the fix)

  1. Check OpenHarmony release notes on gitee.com for version 5.0.4 or later releases
  2. Verify if CVE-2025-24925 is specifically addressed in the release notes
  3. If available, upgrade the OpenHarmony installation to version 5.0.4 or later
  4. After upgrade, verify the memory leak fix is applied by reviewing the specific code changes in the commit
Caveat Check release notes for any breaking changes between 5.0.3 and the target version before upgrading
