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 10 software. The lguicc software (for the LG Universal Integrated Circuit Card) allows attackers to bypass intended access restrictions on property values. The LG ID is LVE-SMP-200020 (September 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

This vulnerability in the LG Universal Integrated Circuit Card (lguicc) software on Android OS 10 devices allows attackers to bypass intended access restrictions on property values. The issue enables unauthorized access to protected configuration or system properties related to the UICC/SIM card functionality, which could be chained with other attacks for further device compromise.

MitigationApply the vendor-provided security patch (LG LVE-SMP-200020, September 2020) via official LG firmware updates for affected devices. Organizations should inventory impacted LG devices and deploy updates through their mobile device management infrastructure.

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 exactly 10.0
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Android version shows 10.0 exactly - other versions are not affected
  2. Confirm LG lguicc component is installed
    Check for the lguicc package via 'pm list packages | grep lguicc' or inspect /system/app/lguicc/ via ADB shell if present
    Affected if The lguicc package exists on the device - the flaw is in this LG-specific component
  3. Check UICC property access permissions
    Inspect the lguicc configuration files in /data/data/com.lge.lguicc/ or /system/etc/lguicc/ for overly permissive access controls on UICC/SIM properties
    Affected if Protected UICC/SIM system properties are readable without proper authorization - the vulnerability allows this bypass

A device is affected if it runs Android 10.0 on an LG device with the lguicc component present and has the vulnerable permission configuration that allows unauthorized UICC property access.

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

Apply the vendor-provided security patch (LG LVE-SMP-200020, September 2020) via official LG firmware updates for affected devices. Organizations should inventory impacted LG devices and deploy updates through their mobile device management infrastructure.

Recommended fix Moderate confidence

Android 11+ (if device is supported by LG)

  1. Check for available system/security updates on the LG device via Settings > System > Software Update or Settings > General > About phone > Software Update
  2. If no update is available, contact LG customer support or your mobile carrier for patch availability information
  3. Consider upgrading to Android 11 or later if the device hardware supports it, as the vulnerability is specific to Android 10.0
  4. Verify the LG security bulletin LVE-SMP-200020 for any carrier-specific patch deployment timelines
Caveat Upgrading to a newer Android version may remove support for some legacy apps or features; verify app compatibility before upgrading
