CVE-2024-38161

Code execution via malicious USB device

Published Aug 13, 2024 · Updated Jul 10, 2025

Heap-based buffer overflow in the Windows Mobile Broadband Driver allows physically proximate attackers to execute code through a malicious USB device. Microsoft identifies the driver and heap-overflow class but has not published the affected routine, malformed field, or missing bounds operation. Physical access to attach a crafted USB device is required, and successful exploitation grants code execution with confidentiality, integrity, and availability consequences.
