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 SystemUI, there is a possible way to unexpectedly enable the external speaker due to a logic error in the code. This could lead to local information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-190199063

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 logic error in Android SystemUI causes the external speaker to unexpectedly enable, leading to potential local information disclosure. Exploitation requires user interaction but no additional privileges. The vulnerability stems from incorrect audio routing logic in the system UI layer.

MitigationApply the vendor patch for CVE-2022-20317 through Android system updates. Until the patch is available, user awareness of unexpected audio output is the only mitigation.

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. Verify Android version is 13.0
    Run 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android version. Confirm the version is exactly 13.0 (not 13.0.1, 13.0.2, or other point releases).
    Affected if Android version is exactly 13.0
  2. Confirm SystemUI package version
    Run 'adb shell dumpsys package com.android.systemui' and look for the versionName or versionCode in the output.
    Affected if SystemUI version corresponds to the unpatched Android 13.0 build.
  3. Check for security patch level
    Run 'adb shell getprop ro.build.version.security_patch' to see the installed security patch date.
    Affected if Security patch level is earlier than the vendor fix for CVE-2022-20317 (typically September 2022 or earlier).

You are affected if running Android version exactly 13.0 with a security patch level prior to the vendor fix for this CVE.
