Detailsinfo

A vulnerability classified as critical was found in BlueZ (the affected version is unknown). Affected by this vulnerability is an unknown code of the component Audio Profile AVRCP. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is 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). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The weakness was presented 12/22/2023 as ZDI-23-1900. The advisory is shared at zerodayinitiative.com. This vulnerability is known as CVE-2023-44431 since 09/28/2023. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/08/2025).

The vulnerability scanner Nessus provides a plugin with the ID 210817 (RHEL 9 : bluez (RHSA-2024:9413)), which helps to determine the existence of the flaw in a target environment.
