CVE-2026-75032
Bluez: bluez: out-of-bounds read in avrcp parse_media_element and parse_media_folder
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.
Fixes and workarounds
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.
