CVE-2024-34727
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 sdpu_compare_uuid_with_attr of sdp_utils.cc, there is a possible out of bounds read due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
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 confidenceA heap buffer overflow in the sdpu_compare_uuid_with_attr function of sdp_utils.cc allows an out-of-bounds read during Bluetooth SDP UUID comparison. This remote information disclosure vulnerability requires no elevated privileges or user interaction to exploit.

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.
-
Check Android versionGo to Settings > About Phone > Android version and note the displayed version numberAffected if The version shown is 12.0, 12.1, 13.0, or 14.0 exactly
-
Check if Bluetooth is enabledOpen Settings > Bluetooth or check the quick settings panel to see if Bluetooth toggle is onAffected if Bluetooth is currently turned on
-
Confirm SDP service is activeThe Bluetooth SDP (Service Discovery Protocol) runs automatically when Bluetooth is enabled - no additional check neededAffected if Bluetooth is enabled, as SDP initializes with any Bluetooth activity
User is affected if their Android version is exactly 12.0, 12.1, 13.0, or 14.0 and Bluetooth is turned on, since the vulnerable sdp_utils.cc code handles SDP UUID comparison whenever Bluetooth is active.

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 vendor security patch (Google Android Security Bulletin). As a workaround, disable Bluetooth when not in use to reduce attack surface.
May 2024 Android Security Bulletin (Android 12, 12.1, 13, and 14)
- Check your current Android version in Settings > About Phone > Android version
- Apply the latest Android security update for your device through Settings > System > Security update > Security update
- For Pixel devices, ensure you have the May 2024 or later security patch level installed
- For other Android devices, check with your device manufacturer for the availability of the May 2024 Android Security Bulletin update
- If your device manufacturer has released an update containing the May 2024 Android Security Bulletin patches, apply it
