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
In libstagefright there is a possible information disclosure due to uninitialized data. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation. Product: AndroidVersions: Android-10Android ID: A-111804142

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

In libstagefright, Android's media framework, there is a vulnerability where uninitialized data can be read and disclosed. This occurs during media file processing and can lead to remote information disclosure without requiring additional execution privileges, though user interaction (such as opening a malicious media file) is needed for exploitation.

MitigationApply the Android security patch for Android-10 that addresses this vulnerability. Organizations should ensure their Android devices receive regular security updates and consider restricting media file handling from untrusted sources until patches are applied.

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 version is exactly 10.0
    Go to Settings > About Phone > Android version, or run 'adb shell getprop ro.build.version.release' via USB debugging
    Affected if Version reports exactly 10.0 (Android Q)
  2. Verify libstagefright component is present
    Run 'adb shell ls -la /system/lib64/libstagefright.so' to confirm the library exists on the device
    Affected if The libstagefright.so library file is present on the system
  3. Confirm media processing is enabled
    Check if any media-handling apps (Gallery, Camera, video players, browsers) are installed and functional on the device
    Affected if Media processing applications are installed and can be used to open media files
  4. Identify if device receives monthly security updates
    Go to Settings > Security > Security update level, or run 'adb shell getprop ro.build.version.security_patch'
    Affected if Security patch level is earlier than the 2019-11-01 patch or is blank/unset

A device is affected if it runs Android 10.0 and processes media files with an unpatched libstagefright component, allowing uninitialized memory disclosure when a specially crafted media file is opened.
