CVE-2023-24944

Adjacent information disclosure via driver type confusion

Published May 9, 2023 · Updated Jul 10, 2025

Type confusion in the Windows Bluetooth driver in affected Windows builds allows physically proximate attackers to read sensitive memory. Microsoft has not published which driver routine accesses a resource using an incompatible type or how crafted Bluetooth traffic reaches it. The attacker must be within Bluetooth range; authentication and user interaction are not required, and the documented impact is memory disclosure only.
