What is CVE-2023-27349?

A vulnerability within the BlueZ Bluetooth protocol stack affects the Audio/Video Remote Control Profile (AVRCP), exposing systems to potential remote code execution attacks. This vulnerability arises from inadequate validation of user-supplied data during AVRCP handling, leading to buffer overflows. When a user connects to a malicious Bluetooth device, an attacker can exploit this flaw to execute arbitrary code within the context of the operating system. Proper security measures should be implemented to mitigate the risks associated with this vulnerability, especially in environments where Bluetooth connectivity is prevalent.
