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 issue was discovered on LG mobile devices with Android OS 7.2, 8.0, 8.1, 9, and 10 software. A stack-based buffer overflow in the logging tool could allow an attacker to gain privileges. The LG ID is LVE-SMP-200005 (April 2020).

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

A stack-based buffer overflow vulnerability exists in the logging tool of LG mobile devices running Android OS versions 7.2, 8.0, 8.1, 9, and 10. This memory corruption flaw can be exploited by an attacker to gain elevated privileges on the affected device.

MitigationApply the vendor patch released by LG (LVE-SMP-200005) through official OTA updates; if patches are unavailable, consider network segmentation or restriction of untrusted app installations to reduce attack surface.

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 device manufacturer
    Check the device settings to confirm the manufacturer is LG. Go to Settings > About Phone > Manufacturer or use command: 'getprop ro.product.manufacturer'
    Affected if Device is not manufactured by LG, this specific vulnerability does not apply
  2. Check Android OS version
    Navigate to Settings > About Phone > Android version, or run: 'getprop ro.build.version.release'
    Affected if Version is 7.2, 8.0, 8.1, 9.0, or 10.0 - these are the affected versions per the CVE
  3. Verify logging tool presence
    Check if the LG logging tool/application is installed on the device. Look for LG logging apps in the app drawer or list installed packages using: 'pm list packages | grep -i log'
    Affected if The logging tool is present on the device - the vulnerability exists in this component
  4. Confirm patch status
    Check if LG security patch LVE-SMP-200005 has been applied. Go to Settings > About Phone > Software Info > Security patch level, or run: 'getprop ro.build.version.security_patch'
    Affected if Security patch level is earlier than May 2020 or if the specific LVE-SMP-200005 patch is not listed as installed

The device is affected if it is an LG mobile device running Android 7.2, 8.0, 8.1, 9.0, or 10.0 with the logging tool present and without the LVE-SMP-200005 patch applied.
