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
An improper access control vulnerability in genericssoservice prior to SMR JUN-2021 Release 1 allows local attackers to execute protected activity with system privilege via untrusted applications.

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

This is a local privilege escalation vulnerability in Samsung's genericssoservice component. Local untrusted applications can execute protected activities with system privileges due to improper access control checks, allowing attackers to gain elevated permissions on the device.

MitigationApply the SMR JUN-2021 Release 1 patch which implements proper access control validation in genericssoservice to ensure only authorized applications can invoke protected activities.

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 shell
    Affected if Android version is exactly 10.0 (the only affected version per the provided data)
  2. Identify device vendor
    Check device manufacturer via Settings > About Phone > Manufacturer, or run 'getprop ro.product.manufacturer' via ADB
    Affected if Device is a Samsung device (the vulnerable genericssoservice component is Samsung-specific)
  3. Verify genericssoservice presence
    Run 'pm list packages | grep -i sso' or check for genericssoservice APK in /system/priv-app/ directory via ADB
    Affected if The genericssoservice component is installed on the device
  4. Check security patch level
    Go to Settings > About Phone > Software information > Security patch level, or run 'getprop ro.build.version.security_patch' via ADB
    Affected if Security patch level is earlier than 2021-06-01 (the SMR JUN-2021 Release 1 patch fixes this issue)

Device is affected if it is a Samsung device running Android 10.0 with the genericssoservice component present and a security patch level earlier than June 2021
