"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2026-3141 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)

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

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