What is CVE-2024-23963?
CVE-2024-23963 is a high-severity memory corruption vulnerability in Alpine Halo9, published on 30 Jan 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine Halo9 devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.
The specific flaw exists within the PBAP_DecodeVCARD function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.
Weakness: CWE-94
