high Nessus Plugin ID 337681

Synopsis

The version of VMware Fusion installed on the remote macOS host is affected by an information disclosure vulnerability.

Description

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.

Solution

Upgrade to VMware Fusion 26.0.0 (26H1) or later.
