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 in SumeNNService prior to SMR Aug-2024 Release 1 allows local attackers to start privileged service.

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 SumeNNService allows local attackers to start the service with elevated privileges. This is a local privilege escalation vulnerability where the service does not properly validate or restrict which users can initiate it, potentially allowing unprivileged local users to trigger the service to run with system or administrator-level access.

MitigationApply the SMR Aug-2024 Release 1 patch to SumeNNService to fix the improper privilege management. Additionally, restrict service startup permissions to prevent unprivileged users from starting the service until the patch is applied.

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. Check Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if The version is exactly 13.0 or 14.0
  2. Verify SumeNNService presence
    Check if the SumeNNService exists on the device by searching for it in system services: run 'dumpsys | grep -i sume' via ADB or check /system/bin for the service binary
    Affected if SumeNNService is found running or installed on the device
  3. Inspect service configuration
    Run 'dumpsys service SumeNNService' or check the service's init rc configuration file in /system/etc/init/ to examine startup permissions and user/group settings
    Affected if The service configuration allows unprivileged users (not root/system) to start or interact with the service, or lacks proper user/group restrictions
  4. Check service process privileges
    When the service is running, use 'ps -A | grep sume' via ADB to view the process owner, then cross-reference with expected privileged user (such as system or root)
    Affected if The service runs with elevated privileges (root/system) but permits initiation by any local user without authentication

A device is affected if it runs Android 13.0 or 14.0, contains the SumeNNService, and the service allows unprivileged local users to trigger its execution with elevated system access.

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

Apply the SMR Aug-2024 Release 1 patch to SumeNNService to fix the improper privilege management. Additionally, restrict service startup permissions to prevent unprivileged users from starting the service until the patch is applied.

Recommended fix High confidence

SMR Aug-2024 Release 1

  1. Check for and apply the Samsung SMR (Security Maintenance Release) August 2024 update on your Samsung Android device running version 13.0 or 14.0
  2. Go to Settings > Software update > Download and install to check for available updates
  3. Ensure the installed SMR version is Aug-2024 Release 1 or later which contains the fix for SumeNNService privilege management vulnerability
