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.

The Rocky Linux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1793354956 advisory.

  - BlueZ A2DP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows     network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. An attacker must     first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit     this vulnerability. The specific flaw exists within the handling of the stream endpoints. The issue     results from the lack of proper validation of the length of user-supplied data prior to copying it to a     fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the     context of root. Was ZDI-CAN-29429. (CVE-2026-19774)

  - 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. (CVE-2026-75032)

  - BlueZ sdp-xml.c type confusion via RegisterProfile(ServiceRecord) can crash bluetoothd (local DoS): a     crafted nested ServiceRecord can corrupt the SDP XML parser stack so scalar union data is treated as a     sequence pointer, allowing a local caller to crash bluetoothd. (CVE-2026-80185)

  - A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote     user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that     causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead     to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code     execution. (CVE-2026-80186)

  - AVRCP ListPlayerAttributes double stack overflow in     avrcp_list_player_attributes_rsp/avrcp_get_current_player_value [fedora-all] (CVE-2026-85218)

    Michael Bommarito discovered that BlueZ incorrectly handled codec capability storage in the A2DP profile.
    An attacker could possibly use this issue to cause a stack buffer overflow, resulting in a denial of     service or arbitrary code execution. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu     24.04 LTS and Ubuntu 26.04 LTS. (CVE-2026-19774)

    It was discovered that BlueZ incorrectly handled packet length validation. An attacker could possibly use     this issue to read out of bounds memory, causing a crash or exposing sensitive information.
    (CVE-2026-75032)

    It was discovered that BlueZ incorrectly handled crafted XML input. An attacker could possibly use this     issue to crash BlueZ, resulting in a denial of service. (CVE-2026-80185)

    It was discovered that BlueZ incorrectly parsed remote names from Extended Inquiry Response data. An     attacker could possibly use this issue to cause a stack buffer overflow, resulting in a denial of service     or arbitrary code execution. (CVE-2026-80186)

    Alexandro Calo discovered that BlueZ incorrectly parsed certain responses in the AVRCP profile. An     attacker could possibly use this issue to access out of bounds memory, causing a crash or exposing     sensitive information. (CVE-2026-85218)
