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.

The remote Fedora 43 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-a1cdcc1604 advisory.

    An out-of-bounds read flaw was found in BlueZ in the AVRCP profile implementation. The vulnerability     exists in the parse_media_element() and parse_media_folder() functions in profiles/audio/avrcp.c, where     insufficient validation of packet length fields in GetFolderItems responses allows a malicious Bluetooth     device within range to cause an out-of-bounds memory read. This can result in a crash of the bluetoothd     daemon (denial of service) and potentially expose sensitive heap memory contents.

    This update fixes this issue (CVE-2026-75032)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
