CVE-2025-24304
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 · uneditedin OpenHarmony v5.0.2 and prior versions allow a local attacker cause DOS 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 confidenceOpenHarmony v5.0.2 and prior versions contain an out-of-bounds write vulnerability that can be exploited by a local attacker to cause denial of service. The vulnerability requires local access to the device and results in a crash or unavailable service due to the memory corruption.
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 checksWork through these to decide whether this CVE applies to you.
-
Identify OpenHarmony installationLocate the OpenHarmony system or device in your environment and determine it is running OpenHarmony software (check system information, device inventory, or firmware details)Affected if The system or device is confirmed to be running OpenHarmony
-
Determine installed versionUse system information tools, firmware inspection, or device management interfaces to obtain the exact OpenHarmony version number running on the affected systemAffected if The installed version is 5.0.2 or any version prior to 5.0.2 (versions 5.0.2, 5.0.1, 5.0.0, or older releases)
-
Verify local access contextAssess whether the vulnerable OpenHarmony system is accessible to local attackers (physical access to device, local terminal access, or console access)Affected if The system permits local user access (physical console, debug ports, or local shell access) without sufficient isolation or access controls
-
Confirm vulnerable component is activeDetermine if the OpenHarmony system is operational and the memory management subsystem (where the out-of-bounds write occurs) is in useAffected if The OpenHarmony device is powered on and actively running, making the vulnerability exploitable for denial of service
You are affected if your OpenHarmony installation is version 5.0.2 or earlier and the device permits local access, since the out-of-bounds write can be triggered by a local attacker to cause a crash.

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.
From vendor dataUpgrade to a version newer than v5.0.2 if available, or contact the OpenHarmony security team for patches. If upgrading is not immediately possible, restrict local access to trusted users only.
