CVE-2024-23963

Root code execution via Bluetooth vCard overflow

Published Jan 30, 2025 · Updated Jul 1, 2025

Stack-based buffer overflow in Alpine Halo9 devices allows physically proximate attackers to execute arbitrary code as root over Bluetooth. PBAP_DecodeVCARD copies user-supplied vCard data into a stack-based buffer without first validating its length. Exploitation requires the target to pair with a malicious Bluetooth device; successful execution gains root context.
