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
A remote code execution vulnerability in the Android media framework (libavc). Product: Android. Versions: 6.0. Android ID A-64964675.

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 remote code execution vulnerability exists in Android's media framework component libavc (H.264/AVC codec) affecting Android 6.0. The vulnerability allows remote attackers to execute arbitrary code via specially crafted media files processed by the libavc decoder, likely through a buffer overflow or similar memory corruption issue in the codec parsing logic.

MitigationApply the Android security patch level for the month containing the fix for A-64964675, which addresses the libavc vulnerability in the media framework. For affected embedded devices, update the underlying Android system image and verify media processing functionality post-patch.

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. Confirm Android version is 6.0
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version
    Affected if The version returned is exactly 6.0 (API level 23)
  2. Check if libavc is present on the device
    Look for libavc.so in /system/lib/ or /vendor/lib/ directories using 'find /system/lib -name libavc*'
    Affected if libavc.so exists on the device
  3. Identify applications or processes that use libavc
    Search for apps that process media (video players, camera apps, video editors) or check which apps link to libavc via 'adb shell dumpsys meminfo' for media-related processes
    Affected if Any app that processes H.264 media is installed and used
  4. Check the Android security patch level
    Run 'getprop ro.build.version.security_patch' or check Settings > About Phone > Security patch level
    Affected if The patch level is earlier than the month containing the fix for A-64964675 (the CVE fix date)
  5. Test media processing with untrusted files
    Attempt to decode a specially crafted H.264 file using a media player or the stagefright tool on the device
    Affected if The device can process untrusted media files without crashing or the process completes without error (noting that successful exploitation would cause a crash or unexpected behavior)

A device is affected if it runs Android 6.0, contains the vulnerable libavc library, processes untrusted H.264 media files, and has a security patch level predating the CVE fix.
