CVE-2025-8475: (0Day) (Pwn2Own) Alpine iLX-507 AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability
Alpine iLX-507 AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine iLX-507 devices. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device.
The specific flaw exists within the implementation of the AVRCP protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-26321.
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Mitigate the ZDI-CAN-26321 AVRCP stack-based buffer overflow by preventing target Alpine iLX-507 devices from connecting to untrusted/malicious Bluetooth devices (e.g., restrict/allowlist Bluetooth pairing to trusted devices).
