CVE-2024-23963

Alpine Halo9 Stack-based Buffer Overflow

Published Jan 30, 2025 CVSS 3.1 · 8 High EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Workaround
