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 impeg2_idct_recon_sse42() of impeg2_idct_recon_sse42_intr.c, there is an out of bound write due to a missing bounds check. This could lead to an remote code execution with no additional execution privileges needed. User interaction is needed for exploitation. Product: Android. Versions: 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, 8.1. Android ID: A-70349612.

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 · high confidence

Buffer overflow vulnerability in the MPEG-2 IDCT reconstruction function (impeg2_idct_recon_sse42) where a missing bounds check allows out-of-bounds memory writes, potentially enabling remote code execution. User interaction is required for exploitation.

MitigationApply Android security patches for the affected versions (6.0-8.1) to address the missing bounds check in the MPEG-2 decoder. This is a media framework component that receives patches through monthly Android security updates.

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 Android version
    Go to Settings > About Phone > Android version (or run 'getprop ro.build.version.release' via ADB)
    Affected if Version matches 6.0, 6.0.1, 7.0, 7.1.1, 7.1.2, 8.0, or 8.1
  2. Confirm media framework component present
    Check if the Android media framework library libimsvt_tunnel.so or libmpeg2enc.so exists on the device (typically in /system/lib/)
    Affected if MPEG-2 decoder libraries are present on the device
  3. Verify MPEG-2 decoding capability
    Attempt to play an MPEG-2 video file or check if any app uses MPEG-2 decoding (check logs for 'impeg2_idct' references using 'logcat | grep impeg2')
    Affected if Device can decode or has decoded MPEG-2 content

User is affected if running Android 6.0-8.1 AND the device has the vulnerable MPEG-2 decoder component that processes media content.
