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 module due to integer overflow in Snapdragon Auto, Snapdragon Connectivity, Snapdragon Mobile, Snapdragon Wearables

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

Integer overflow in the audio module of Qualcomm Snapdragon chips allows memory corruption. The vulnerability stems from insufficient bounds checking on integer values, which can be manipulated to cause buffer overflows or out-of-bounds memory writes in the audio processing component.

MitigationApply vendor-supplied firmware patches from Qualcomm//device OEMs. Prioritize updating mobile devices, wearables, and automotive systems using affected Snapdragon chipsets.

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 Snapdragon chip model
    Check the device specifications or system information to determine the exact Snapdragon chipset model (e.g., via device info settings, /proc/cpuinfo on Android, or system firmware logs)
    Affected if The chip model matches any of: Ar8035, Qca6595au, Qca8081, Qca8337, Sa6155p, Sa8155p, Sa8195p, or SD 8 Gen1 5g
  2. Determine the audio firmware version
    Access the audio module firmware version through the device's service menu, diagnostic logs, or by querying the audio subsystem (e.g., via adb shell dumpsys audio, or checking /vendor/firmware/ for audio-related firmware files)
    Affected if The audio firmware version is present and corresponds to the affected chip models (all versions of these chips are vulnerable)
  3. Verify the audio processing component is active
    Check if the audio HAL (Hardware Abstraction Layer) or audio daemon is running and processing audio data (e.g., via process list, service status, or audio hardware state)
    Affected if The audio module is actively processing audio files or streams, which triggers the vulnerable code path
  4. Check for accessible audio input/output interfaces
    Inspect whether the device exposes audio interfaces (e.g., microphone, speaker, Bluetooth audio) that exercise the vulnerable audio processing component
    Affected if Any audio input or output functionality is enabled and accessible on the device

A device is affected if it uses any of the listed Qualcomm Snapdragon chip models (Ar8035, Qca6595au, Qca8081, Qca8337, Sa6155p, Sa8155p, Sa8195p, or SD 8 Gen1 5g) and has the audio processing component active, since all firmware versions of these chips are vulnerable to the integer overflow in the audio module.
