CVE-2024-39806
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 v4.1.0 and prior versions allow a local attacker cause information leak through out-of-bounds Read.
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 v4.1.0 and prior versions contain an out-of-bounds read vulnerability that allows a local attacker to read sensitive information from memory locations outside the intended buffer boundaries. This information disclosure occurs due to insufficient bounds checking in the affected code path.
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 installationDetermine if OpenHarmony is present in your environment. This may be embedded in IoT devices, smart TVs, or other connected devices running OpenHarmony OS. Check device documentation or system information for 'OpenHarmony' or 'HarmonyOS' references.Affected if OpenHarmony is confirmed to be installed on the device or system
-
Determine installed OpenHarmony versionRetrieve the OpenHarmony version number from your device. Common methods include: checking system settings > about device, using 'getprop' or 'cat /proc/version' on the device shell if accessible, or consulting vendor documentation for version information.Affected if The version cannot be determined or is confirmed to be <= 4.1.0
-
Verify local access controlsSince this vulnerability requires a local attacker to exploit, assess whether untrusted or unauthorized local users have shell access or the ability to execute code on the affected device.Affected if Untrusted local users have shell access or code execution capability on the device
-
Check for vendor firmware updatesConsult the device vendor or OpenHarmony community to confirm if a firmware or software update beyond v4.1.0 has been released that addresses CVE-2024-39806.Affected if No patch beyond v4.1.0 is available from the vendor or the installed version remains at v4.1.0 or lower
A system is affected if it runs OpenHarmony version 4.1.0 or prior AND has the vulnerable bounds-checking code path enabled, with potential exposure to local untrusted users.

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 dataApply the vendor patch for CVE-2024-39806 when available; upgrade to a patched version of OpenHarmony beyond v4.1.0. If immediate patching is not possible, minimize exposure by restricting local access to trusted users only.
