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
Deserialization mismatch vulnerability in the DSoftBus module Impact: Successful exploitation of this vulnerability may affect service integrity.

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 deserialization mismatch vulnerability exists in the DSoftBus module where the code expects one data format or type during deserialization but receives another, potentially allowing manipulation of data structures or service operations that affect integrity.

MitigationApply vendor patches for DSoftBus module; implement strict type checking and validation on deserialized objects before processing to prevent mismatch exploitation.

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 checks

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

  1. Identify the operating system
    Run 'getprop ro.build.version.emui' or 'getprop ro.build.version.harmonyos' to determine if the device runs Huawei Emui or Harmonyos
    Affected if The OS is Huawei Emui 12.0.0, 13.0.0, or 14.0.0; or Harmonyos 2.0.0, 2.1.0, 3.0.0, 3.1.0, or 4.0.0
  2. Confirm the DSoftBus module is present
    Check for the DSoftBus service or library files on the system - look for 'dsoftbus' in /system/lib/ or /system/vendor/lib/ or check service list via 'hdc shell bm dump -a'
    Affected if The DSoftBus module is installed and running on the device
  3. Verify deserialization is enabled
    Examine the DSoftBus configuration or logs to determine if IPC deserialization features are actively used for inter-process communication
    Affected if DSoftBus deserialization for data exchange between services is enabled and active
  4. Check for type mismatch indicators
    Review DSoftBus logs for deserialization errors or type mismatch warnings using 'hdc shell hilog -d 1000 | grep -i dsoftbus' or check for crash dumps involving deserialization
    Affected if Logs show type mismatch errors during deserialization operations or unexpected data structure handling

A user is affected if their device runs Emui 12.0.0, 13.0.0, or 14.0.0 or Harmonyos 2.0.0 through 4.0.0 and the DSoftBus module with deserialization is active.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patches for DSoftBus module; implement strict type checking and validation on deserialized objects before processing to prevent mismatch exploitation.

Recommended fix Moderate confidence

Latest available EMUI or HarmonyOS release (newer than 14.0.0 for EMUI, newer than 3.1.0 for HarmonyOS)

  1. 1. Identify the current EMUI or HarmonyOS version on the affected device via Settings > About Phone
  2. 2. Check for available system updates via Settings > System & Updates > Software Update
  3. 3. Apply all available security updates to address the deserialization vulnerability in the DSoftBus module
  4. 4. Verify the device is running a version newer than the affected versions (EMUI >14.0.0 or HarmonyOS >3.1.0) after update
