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 Bluetooth, there is a possible out of bounds write due to an integer overflow. This could lead to remote code execution over Bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-13Android ID: A-233069336

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 vulnerability in the Android Bluetooth stack allows remote code execution through an integer overflow that leads to an out of bounds write. The flaw can be exploited without requiring user interaction or elevated privileges.

MitigationApply the Android-13 security patch level that addresses this vulnerability. Since this is a platform-level Bluetooth vulnerability, patching requires updating the system firmware rather than application-level changes.

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
    Go to Settings > About Phone and check the Android version field. Alternatively, run 'getprop ro.build.version.release' via ADB shell.
    Affected if The installed Android version equals 13.0 exactly (not 13.0.x or higher)
  2. Confirm Bluetooth is enabled
    Check Settings > Bluetooth to see if Bluetooth is turned on. Alternatively, run 'settings get global bluetooth_on' via ADB shell (returns 1 if enabled).
    Affected if Bluetooth is currently enabled on the device
  3. Check Security Patch Level
    Go to Settings > About Phone > Security Patch Level. Alternatively, run 'getprop ro.build.version.security_patch' via ADB shell.
    Affected if The Security Patch Level is earlier than the Android-13 patch that addresses this vulnerability, meaning the device has not received the fix

The device is affected if Android version is exactly 13.0, Bluetooth is enabled, and the installed Security Patch Level predates the fix for this CVE.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the Android-13 security patch level that addresses this vulnerability. Since this is a platform-level Bluetooth vulnerability, patching requires updating the system firmware rather than application-level changes.

Recommended fix Moderate confidence

Android 13.x with latest security patch (October 2022 or later)

  1. Check your device's current Android security patch level in Settings > About Phone > Android version
  2. Go to Settings > System > Security update and check for available updates
  3. Install the latest Android 13 security update (Android 13 security patch level from October 2022 or later)
  4. Verify the update was installed successfully by checking the Android version and security patch level again
