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 validation vulnerability in ucmRetParcelable of KnoxSDK prior to SMR Jul-2022 Release 1 allows attackers to launch certain activities.

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 an improper validation vulnerability in the ucmRetParcelable function within Samsung's KnoxSDK. The lack of proper input validation in this parcelable-related component (used for Android inter-process communication) allows attackers to launch certain activities on affected devices. This affects KnoxSDK versions prior to the July 2022 SMR release.

MitigationUpdate KnoxSDK to SMR Jul-2022 Release 1 or later to obtain the patched version with proper validation in ucmRetParcelable.

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 Android version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if The version is 10.0, 11.0, or 12.0 (this is a prerequisite for being in the affected scope)
  2. Verify Samsung KnoxSDK is installed
    Check for Knox-related system apps or packages. On Samsung devices, look for 'com.sec.knox' or 'com.samsung.android.knox' in the package list via 'adb shell pm list packages | grep knox'
    Affected if KnoxSDK packages are present on the device
  3. Determine the installed KnoxSDK version
    Check the Knox version via 'adb shell dumpsys package com.samsung.android.knox' or look in Settings > Apps > Knox > Version
    Affected if The KnoxSDK version predates the July 2022 SMR release (patched version is SMR Jul-2022 Release 1 or later)
  4. Confirm Knox is active and ucmRetParcelable feature is enabled
    Verify Knox is provisioned and active by checking 'adb shell dumpsys package com.samsung.android.knox' for active license state or check if UCM (Unified Credential Manager) service is running
    Affected if Knox is enabled and the ucmRetParcelable parcelable component is accessible to applications

A device is affected if it runs Android 10, 11, or 12, has Samsung KnoxSDK installed with a version earlier than the July 2022 SMR release, and has Knox features enabled.

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

Update KnoxSDK to SMR Jul-2022 Release 1 or later to obtain the patched version with proper validation in ucmRetParcelable.

Recommended fix Moderate confidence

SMR Jul-2022 Release 1

  1. Identify if the device uses Samsung KnoxSDK
  2. Check current KnoxSDK version on the device
  3. Update to SMR Jul-2022 Release 1 or later which contains the fix for the ucmRetParcelable improper validation vulnerability
  4. Verify the update was successfully applied
