| Name | CVE-2023-44431 |
| Description | BlueZ Audio Profile AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious device. The specific flaw exists within the handling 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-19909. |
