Detailsinfo

A vulnerability, which was classified as critical, was found in Alpine iLX-507 6.0.000. This affects an unknown part of the component AVRCP Protocol. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

It is possible to read the advisory at zerodayinitiative.com. This vulnerability is uniquely identified as CVE-2025-8475 since 08/01/2025. The exploitability is told to be easy. The attack needs to be done within the local network. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/05/2025).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
