Kernel code execution via AVDTP integer underflow
Published May 9, 2023 · Updated Jul 10, 2025
Heap-based buffer overflow in the Windows Bluetooth driver allows physically proximate attackers to execute code in the kernel via AVDTP packets. AVDTP packet processing fails to validate attacker-controlled data, causing an integer underflow before a memory write. Exploitation requires low privileges and user interaction because the target must connect to a malicious Bluetooth device; successful exploitation yields kernel-level execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
