CVE-2022-20283
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 · uneditedIn 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 confidenceA 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.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify Android version is 13.0Go 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)
-
Confirm Bluetooth is enabledCheck 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
-
Check Security Patch LevelGo 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.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scopedApply 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.
Android 13.x with latest security patch (October 2022 or later)
- Check your device's current Android security patch level in Settings > About Phone > Android version
- Go to Settings > System > Security update and check for available updates
- Install the latest Android 13 security update (Android 13 security patch level from October 2022 or later)
- Verify the update was installed successfully by checking the Android version and security patch level again
