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 the common permission is upgraded to root and sensitive information leak through double 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 confidence

A double-free vulnerability in OpenHarmony v4.1.0 and prior versions allows a local attacker to escalate common user permissions to root privileges and leak sensitive information through the memory corruption.

MitigationUpgrade OpenHarmony to a version beyond v4.1.0 that contains the fix, or apply vendor-provided security patches addressing the double-free vulnerability in the permission handling 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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify OpenHarmony installation and version
    Check the system for OpenHarmony by examining system information files (e.g., /etc/os-release, version files in /system or /vendor), or use commands like 'getprop' on Android-based builds, 'cat /proc/version', or check boot messages for OpenHarmony version strings
    Affected if The installed version matches 4.0.x or 4.1.x (within the >= 4.0, <= 4.1 range)
  2. Verify the permission handling component is present
    Inspect the system's permission management binaries or services - look for permission-related daemons, SELinux/AppArmor managers, or account management services that handle user privilege escalation
    Affected if The permission handling component exists and is the stock version shipped with the affected OpenHarmony releases
  3. Check for double-free indicators in permission service logs
    Review system logs (dmesg, logcat, or /var/log messages) for memory corruption errors, double-free corruption warnings, or unexpected crashes in permission-related processes
    Affected if Logs show frequent crashes, memory corruption, or heap errors in permission handling processes
  4. Confirm user privilege boundary is accessible
    Test the local privilege escalation path by checking if unprivileged users can trigger permission management operations that involve memory allocation/deallocation cycles
    Affected if The permission handling component processes requests from non-root users without additional integrity checks

A user is affected if their OpenHarmony installation is version 4.0.x or 4.1.x and includes the vulnerable permission handling component in its default configuration.
