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
Use After Free (UAF) vulnerability in the Vdecoderservice service. Successful exploitation of this vulnerability may cause the image decoding feature to perform abnormally.

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 Use After Free (UAF) vulnerability in the Vdecoderservice component allows an attacker to access freed memory during image decoding operations, potentially leading to arbitrary code execution or service disruption.

MitigationObtain and apply the vendor-supplied patch for Vdecoderservice; if unavailable, consider service isolation, updated memory protection tools, or compensating controls until a fix is available.

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 the installed OS version
    Check system settings or run 'getprop ro.build.emui_version' for Emui or 'getprop ro.build.version.harmonyos' for Harmonyos
    Affected if The version is exactly 12.0.0 (Emui) or 2.0.0 (Harmonyos)
  2. Locate the Vdecoderservice component
    Search for vdecoderservice process or service file in /system/bin/, /vendor/bin/, or through process listing commands like 'ps -A | grep -i vdecoder'
    Affected if The Vdecoderservice binary or process is present on the device
  3. Verify image decoding functionality is in use
    Check if applications or system services invoke the Vdecoderservice for image decoding by monitoring system logs or examining codec configuration files in /etc/ or /vendor/etc/
    Affected if Image decoding operations route through the vulnerable Vdecoderservice component

The environment is affected only if running Emui 12.0.0 or Harmonyos 2.0.0 AND the Vdecoderservice component is present and handling image decoding operations.
