Bluez: bluez: out-of-bounds read in avrcp parse_media_element and parse_media_folder
CVE-2026-75032 is fixed in 11 products on 1 platform, first by DEBIAN-CVE-2026-75032, released August 30, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
