CVE-2024-23935

Root code execution via DecodeUTF7 buffer overflow

Published Sep 28, 2024 · Updated Oct 3, 2024

Stack-based buffer overflow in Alpine Halo9 6.0.000 allows physically proximate attackers to execute arbitrary code via Bluetooth. DecodeUTF7 copies user-supplied data into a stack buffer without validating its length, allowing the input to overwrite adjacent stack memory. Exploitation requires pairing a malicious Bluetooth device with the unit, and successful code execution runs in the root context.
