Vulnerability from github – Published: 2026-08-18 15:31 – Updated: 2026-08-18 15:31

Details

A flaw was found in BlueZ. Insufficient validation of packet length fields in GetFolderItems responses within the Audio/Video Remote Control Profile (AVRCP) implementation allows a malicious Bluetooth device within range to cause an out-of-bounds memory read. This vulnerability, affecting the parse_media_element() and parse_media_folder() functions, can lead to a crash of the bluetoothd daemon, resulting in a Denial of Service (DoS). It could also potentially expose sensitive heap memory contents. Exploitation requires user interaction to pair with the malicious device.

Severity

6.3 (Medium)


                  
                    CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H
