What is CVE-2025-5475?

The Sony XAV-AX8500 is susceptible to a vulnerability due to improper handling of Bluetooth packets, allowing network-adjacent attackers to execute arbitrary code. Attackers must pair a malicious Bluetooth device with the target system to exploit this flaw. The vulnerability arises from insufficient validation of user-supplied data, leading to an integer overflow that could be exploited to write to memory and execute code in the context of the elysian-bt-service process. This exposure highlights significant security risks for users relying on Bluetooth functionality.
