"The version of VMware Fusion installed on the remote macOS host is 25.x (25H2) prior to 26.0.0 (26H1). It is,
therefore, affected by a vulnerability as referenced in the VMSA-2026-0006.1 advisory:

  - VMware ESX, Workstation, and Fusion contain an out-of-bounds read vulnerability. A malicious actor
    with VM deployment privileges could trigger an out-of-bounds read, potentially leading to information
    disclosure or more likely a Denial-of-Service (DoS) condition of the host process. On Workstation and
    Fusion, the impact of this vulnerability is restricted to information disclosure. (CVE-2026-41703)

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