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
Out of bound memory access while playing music playbacks with crafted vorbis content due to improper checks in header extraction in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon IoT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables, Snapdragon Wired Infrastructure and Networking

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 Qualcomm Snapdragon processors where improper bounds checking during vorbis audio header extraction allows out-of-bounds memory access when processing crafted vorbis audio files, leading to potential code execution.

MitigationApply vendor-supplied firmware updates from Qualcomm to affected Snapdragon-based devices. Prioritize mobile phones, IoT devices, and wearables given the fragmented update ecosystem.

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 processor model
    On Android devices, check /proc/cpuinfo for the processor name, or use system information apps to identify the chipset. Look for identifiers such as APQ8009, APQ8009W, APQ8017, APQ8030, APQ8037, APQ8052, APQ8053, or APQ8056.
    Affected if The device uses any of the listed APQ processor models (Apq8009, Apq8009w, Apq8017, Apq8030, Apq8037, Apq8052, Apq8053, Apq8056).
  2. Confirm the SoC/firmware is from Qualcomm
    Verify the device runs a Qualcomm Snapdragon-based system-on-chip. Check device specifications, boot logs, or baseband information (/proc/bootinfo or *#*#4636#*#* on Android).
    Affected if The device firmware is based on Qualcomm Snapdragon processors.
  3. Check if vorbis audio decoding is supported
    Verify that the device supports or has enabled vorbis audio codec. This can be checked by examining audio codec support in system information, or by attempting to play a vorbis audio file (.ogg) and observing if decoding occurs.
    Affected if Vorbis audio decoding is enabled and the device processes vorbis audio files.
  4. Review baseband and firmware version
    Check the baseband version (in Android settings under About Phone > Baseband version) or modem firmware version. Compare against any available version information from the device manufacturer.
    Affected if The firmware version is an unpatched release for the listed APQ processors (all versions are affected per the advisory).

A device is affected if it contains any of the affected APQ processors (Apq8009, Apq8009w, Apq8017, Apq8030, Apq8037, Apq8052, Apq8053, Apq8056) and supports vorbis audio processing, as the vulnerability allows code execution when processing crafted vorbis audio files.
