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
btif_config.c in Bluetooth in Android 6.x before 2016-03-01 allows remote attackers to cause a denial of service (memory corruption and persistent daemon crash) by triggering a large number of configuration entries, and consequently exceeding the maximum size of a configuration file, aka internal bug 26071376.

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

A memory corruption vulnerability exists in btif_config.c within Android 6.x Bluetooth stack. Remote attackers can trigger creation of an excessive number of Bluetooth configuration entries, causing the config file to exceed its maximum size limit. This results in memory corruption and a persistent crash of the Bluetooth daemon (denial of service).

MitigationApply Android security patch level 2016-03-01 or later to devices running Android 6.x; this is a platform-level vulnerability requiring a system update rather than application-level remediation.

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
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 6.0 or 6.0.1
  2. Confirm Bluetooth is enabled
    Check if Bluetooth is turned on in Settings > Bluetooth, or run 'settings get global bluetooth_on' via ADB shell
    Affected if Bluetooth is enabled (value is 1) and the device is running an affected Android version
  3. Inspect Bluetooth daemon status
    Check if btdaemon or bluetoothd process is running via 'ps -A | grep -i bluetooth' or check for recent crashes in logcat with 'logcat -d | grep -i btif'
    Affected if Bluetooth daemon has crashed repeatedly or shows memory corruption errors related to btif_config

Device is affected if running Android 6.0 or 6.0.1 with Bluetooth enabled, and Bluetooth daemon exhibits crashes or corruption linked to the config subsystem
