What is CVE-2026-75032?

A vulnerability in the BlueZ Bluetooth stack allows for insufficient validation of packet length fields in GetFolderItems responses within the Audio/Video Remote Control Profile (AVRCP). This flaw enables a nearby malicious Bluetooth device to initiate an out-of-bounds memory read, potentially leading to a crash of the bluetoothd daemon. The exploitation of this vulnerability, particularly affecting the parse_media_element() and parse_media_folder() functions, can result in a Denial of Service (DoS) and may disclose sensitive heap memory contents. User interaction is required to pair with the malicious device for successful exploitation.
