CVE-2026-75032

Bluez: bluez: out-of-bounds read in avrcp parse_media_element and parse_media_folder

Published Aug 18, 2026 CVSS 3.1 · 6.3 Medium EPSS < 1% KEV · Not listed
Description
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.

Remediation

Vendor Workaround

Disable the AVRCP Bluetooth profile if it is not needed, or restrict Bluetooth pairing to trusted devices only. On systems where Bluetooth is not required, disable the Bluetooth subsystem entirely.
