CVE-2024-3759
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 v4.0.0 and prior versions allow a local attacker arbitrary code execution in TCB through use after free.
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 confidenceA use-after-free vulnerability in OpenHarmony v4.0.0 and prior versions allows a local attacker to achieve arbitrary code execution within the Trusted Computing Base (TCB). The vulnerability stems from improper memory management where memory is accessed after being freed, leading to potential code execution in the most privileged system component.

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.
-
Confirm OpenHarmony is installedCheck the operating system name and version information on the device or system. On OpenHarmony devices, this is typically found in system settings under 'About device' or by checking the system properties file.Affected if The system is running OpenHarmony as its operating system
-
Identify the installed OpenHarmony versionRetrieve the exact version number of the OpenHarmony installation. This can be done through system information utilities, build.prop files, or device information menus depending on the device form factor.Affected if The installed version is anything less than 4.0.1 (e.g., 4.0.0, 3.x versions, or earlier)
-
Verify the TCB component is presentCheck if Trusted Computing Base (TCB) components are enabled or running on the system. This may involve reviewing active system services or security-related modules that operate at the highest privilege level.Affected if TCB components are present and operational on the affected version
-
Confirm local access to the systemVerify that local attacker access is possible by checking which users or processes have shell or terminal access to the device.Affected if Untrusted local users or processes can execute commands on the system
A system is affected if it runs OpenHarmony version 4.0.0 or any prior version, has TCB components active, and allows local attacker access to the system.

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 · scoped4.0.1
Apply vendor-supplied patches for OpenHarmony to address the use-after-free vulnerability in TCB components; until patched, minimize local attack surface and restrict access to untrusted applications.
OpenHarmony 4.0.1
- Upgrade OpenHarmony to version 4.0.1 or later to resolve the use-after-free vulnerability
- Verify the upgrade by checking the system version after the update completes
- Review the OpenHarmony 4.0.1 release notes to confirm the vulnerability fix is included
