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
Memory Corruption in Audio while playing amrwbplus clips with modified content.

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

Memory corruption vulnerability in the audio playback subsystem when processing AMR-WB+ audio files with modified content. The vulnerability is triggered by specially crafted/malformed audio clips that cause memory corruption during parsing or decoding of the AMR-WB+ format.

MitigationApply vendor patches for the affected audio component; avoid playing AMR-WB+ audio files from untrusted or unknown sources until the patch is 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. Identify the Qualcomm chipset model
    Check system information via 'cat /proc/cpuinfo' or 'dmesg | grep -i qualcomm' to determine the exact chipset (Apq8009, Apq8017, Apq8096au, Aqt1000, Ar8031, Ar8035, Csra6620, or Csra6640)
    Affected if The chipset matches any of the eight affected models (Apq8009, Apq8017, Apq8096au, Aqt1000, Ar8031, Ar8035, Csra6620, Csra6640)
  2. Verify AMR-WB+ audio codec support
    Check if the AMR-WB+ decoder is loaded or available on the system - look for audio codec modules via 'ls /lib/modules/$(uname -r)/kernel/sound/' or check /proc/asound/codecs for codec presence
    Affected if The AMR-WB+ codec is loaded or listed as available in the audio subsystem
  3. Check audio firmware version
    Examine audio processor firmware version if accessible - commands like 'cat /sys/firmware/devicetree/base/model' or checking /proc/bootinfo may reveal firmware version details
    Affected if The firmware version cannot be determined or is earlier than any vendor patch date (no patches have been publicly released for this CVE based on provided data)
  4. Identify AMR-WB+ audio file processing capability
    Determine if any application on the system can process AMR-WB+ audio files - check for AMR-WB+ support in media players or audio libraries via 'ffmpeg -codecs 2>/dev/null | grep -i amr' or similar audio tool
    Affected if The system has capability to decode or play AMR-WB+ audio files from any source

You are affected if your device uses any of the eight listed Qualcomm chipsets AND has AMR-WB+ audio playback capability enabled, since all firmware versions of these chipsets are vulnerable and the flaw triggers during AMR-WB+ file processing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
