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
Integer overflow vulnerability in Samsung decoding library for video thumbnails prior to SMR Dec-2022 Release 1 allows local attacker to perform Out-Of-Bounds Write.

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

An integer overflow vulnerability exists in Samsung's video thumbnail decoding library in versions prior to SMR Dec-2022 Release 1. The overflow allows a local attacker to trigger an out-of-bounds write by providing a specially crafted video file that causes incorrect memory allocation sizing, potentially leading to code execution or denial of service.

MitigationApply the Samsung SMR Dec-2022 Release 1 or later security update, which patches the integer overflow in the video thumbnail decoding library. For enterprise device fleets, ensure all affected devices receive the security patch through standard update mechanisms.

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 OS version
    Go to Settings > About Phone and verify the Android version. On command line, run: 'getprop ro.build.version.release'
    Affected if The version is exactly 10.0, 11.0, 12.0, or 13.0
  2. Verify Samsung video thumbnail library presence
    Check for the existence of Samsung thumbnail decoding libraries in /system/lib/ or /vendor/lib/ directories. Look for files containing 'thumbnail' or 'svc' in the library path.
    Affected if Samsung video thumbnail decoding library is present on the device
  3. Confirm security patch level
    Go to Settings > About Phone > Security Patch Level, or run: 'getprop ro.build.version.security_patch'
    Affected if The security patch level is earlier than December 2022 or the SMR Dec-2022 Release 1 patch is not applied
  4. Check for video file processing access
    Verify if applications can access and process video files that would trigger thumbnail generation. Check app permissions for media storage access.
    Affected if The device can process video files through apps that generate thumbnails

A device is affected if it runs Android version 10.0, 11.0, 12.0, or 13.0 AND contains the Samsung video thumbnail decoding library AND has not received the Samsung SMR Dec-2022 Release 1 security patch.

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

Apply the Samsung SMR Dec-2022 Release 1 or later security update, which patches the integer overflow in the video thumbnail decoding library. For enterprise device fleets, ensure all affected devices receive the security patch through standard update mechanisms.

Recommended fix Moderate confidence

SMR Dec-2022 Release 1 (December 2022 Samsung Security Patch)

  1. Check if your Samsung device is eligible for security updates by visiting security.samsungmobile.com
  2. Navigate to the product security center and locate the SMR Dec-2022 Release 1 security patch information
  3. Verify your current Android version (10.0, 11.0, 12.0, or 13.0) matches the affected versions
  4. Check for system updates on your Samsung device: Settings > Software Update > Download and Install
  5. Apply the December 2022 Samsung Security Maintenance Release (SMR) update which contains the fix for CVE-2022-39907
  6. After updating, confirm the patch level reflects December 2022 or later in Settings > About Phone > Software Information
Caveat Standard security update risks apply; ensure device is charged and connected to Wi-Fi before updating
