Summary
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. Red Hat ships BlueZ in Red Hat Enterprise Linux and related products.
Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H). Weakness: CWE-125.

Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; and 1 more.
