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 avrc_pars_browse_rsp of avrc_pars_ct.cc, there is a possible out of bounds read due to a missing bounds check. This could lead to remote information disclosure over Bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android-8.0 Android-8.1 Android-9. Android ID: A-111451066.

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

An out-of-bounds read vulnerability exists in the avrc_pars_browse_rsp function of avrc_pars_ct.cc within Android's Bluetooth AVRCP (Audio/Video Remote Control Profile) implementation. The missing bounds check during browse response parsing allows a remote attacker to read sensitive memory contents via specially crafted Bluetooth packets without any user interaction or elevated privileges.

MitigationApply the Android security patch for the corresponding Android ID A-111451066, which includes the bound checks in the avrc_pars_ct.cc file. Organizations should prioritize patching Android 8.0, 8.1, and 9 devices.

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. Check Android OS version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if Version is 8.0, 8.1, or 9.0
  2. Verify Bluetooth is enabled
    Check Settings > Bluetooth, or run 'settings get global bluetooth_on' via ADB
    Affected if Bluetooth is turned on (value is 1)
  3. Identify AVRCP profile usage
    Run 'dumpsys bluetooth_manager' via ADB to list active Bluetooth profiles and connected devices; look for avrcp entries in the output
    Affected if AVRCP profile is active or any Bluetooth device is connected using audio/video control
  4. Confirm vulnerable component exists
    Check if the Bluetooth stack includes the avrc_pars_ct.cc module by examining system logs for avrc parsing activity, or verify the Bluetooth firmware version via 'dumpsys bluetooth_logging'
    Affected if AVRCP browse response parsing is occurring on the device

The environment is affected if the device runs Android 8.0, 8.1, or 9.0 with Bluetooth enabled and AVRCP profile functionality in use.
