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 input validation vulnerability in DualOutFocusViewer prior to SMR Nov-2022 Release 1 allows local attacker to perform an arbitrary code execution.

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 · high confidence

Improper input validation in Samsung's DualOutFocusViewer (prior to SMR Nov-2022 Release 1) allows a local attacker to execute arbitrary code. The vulnerability stems from insufficient validation of user-supplied input data, which can be exploited to inject and execute malicious code on the affected device.

MitigationApply the SMR Nov-2022 Release 1 security update or later to address the improper input validation vulnerability in DualOutFocusViewer.

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. Verify Android version is 11.0 or 12.0
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.sdk' and 'getprop ro.build.version.release'
    Affected if Android version equals 11.0 or 12.0 exactly
  2. Confirm device is Samsung
    Check manufacturer via Settings > About Phone > Manufacturer, or run 'getprop ro.product.manufacturer'
    Affected if Manufacturer is Samsung (required for SMR updates)
  3. Check if DualOutFocusViewer component exists
    List installed packages via 'pm list packages | grep dualoutfocus' or check for the app in /system/app/ or /data/app/ directories
    Affected if DualOutFocusViewer package or app is present on the device
  4. Check Samsung Maintenance Release (SMR) version
    Go to Settings > About Phone > Software information > Build number, or run 'getprop ro.build.version.sem'
    Affected if SMR version is prior to Nov-2022 Release 1 (SMR date code earlier than Nov-2022)

Device is affected if it is a Samsung device running Android 11.0 or 12.0 with DualOutFocusViewer present and SMR version before Nov-2022 Release 1.

Mitigation

Apply the SMR Nov-2022 Release 1 security update or later to address the improper input validation vulnerability in DualOutFocusViewer.

Recommended fix High confidence

SMR Nov-2022 Release 1

  1. 1. Verify the device is a Samsung Galaxy device running Android 11.0 or 12.0
  2. 2. Navigate to Settings > About Phone on the device
  3. 3. Check the Android version and confirm it matches 11.0 or 12.0
  4. 4. Navigate to Settings > Software Update
  5. 5. Tap 'Download and Install' to check for the November 2022 security update (SMR Nov-2022 Release 1)
  6. 6. Ensure the DualOutFocusViewer app is updated as part of the SMR Nov-2022 Release 1 patch
  7. 7. Verify the security patch level reflects November 2022 or later in Settings > About Phone > Software Information
