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
Improper privilege management vulnerability in MMIGroup prior to SMR Aug-2023 Release 1 allows code execution with privilege.

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

Improper privilege management in MMIGroup allows an attacker to execute code with elevated privileges, enabling potential unauthorized access and full system compromise.

MitigationUpgrade MMIGroup to SMR Aug-2023 Release 1 or later to obtain the patched version with proper privilege management controls.

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 Android version
    Check the device settings under Settings > About Phone > Android version or use 'getprop ro.build.version.release' via ADB shell
    Affected if The Android version is 12.0 or 13.0 specifically
  2. Locate MMIGroup application
    Check for the MMIGroup package in /data/data or /system/priv-app using 'pm list packages | grep mmi' via ADB shell
    Affected if MMIGroup application is installed on the device
  3. Determine MMIGroup version
    Use 'dumpsys package com.samsung.android.mmi' or check the APK version in /system/priv-app/MMIGroup/ via ADB
    Affected if The MMIGroup version is the pre-patched version from before August 2023 Release 1
  4. Check for elevated privilege execution
    Review app permissions via 'dumpsys package com.samsung.android.mmi' and audit any root or system-level processes spawned by MMIGroup
    Affected if MMIGroup holds or requests elevated system privileges beyond standard app permissions
  5. Verify privilege management controls
    Inspect MMIGroup service configurations in /system/priv-app/MMIGroup/ or via 'dumpsys activity services' for MMI-related services
    Affected if The service does not implement proper privilege separation or validation checks

A user is affected if they are running Samsung Android 12.0 or 13.0 with a pre-August-2023 Release 1 version of MMIGroup that exhibits improper privilege management.
