VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to leak memory from the vmx process.

Reports indicate these vulnerabilities have been exploited in the wild and could lead to VM escape. Apply available updates immediately.

The version of VMware ESXi installed on the remote host is 7.0 prior to 7.0 Update 3s, 8.0 Update 2 prior to 8.0 Update 2d, or 8.0 Update 3 prior to 8.0 Update 3d. It is, therefore, affected by an information disclosure vulnerability:

  - VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read     in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to     leak memory from the vmx process. (CVE-2025-22226)


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

The version of VMware Workstation installed on the remote host is 17.x prior to 17.6.3. It is, therefore, affected by multiple vulnerabilities:

  - VMware ESXi, and Workstation contain a TOCTOU (Time-of-Check Time-of-Use) vulnerability that leads to an     out-of-bounds write. A malicious actor with local administrative privileges on a virtual machine may exploit this     issue to execute code as the virtual machine's VMX process running on the host. (CVE-2025-22224)     
  - VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read     in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to     leak memory from the vmx process. (CVE-2025-22226)

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

The version of VMware Fusion installed on the remote macOS host is 13.x prior to 13.6.3. It is, therefore, affected by an information disclosure vulnerability:

  - VMware ESXi, Workstation, and Fusion contain an information disclosure vulnerability due to an out-of-bounds read     in HGFS. A malicious actor with administrative privileges to a virtual machine may be able to exploit this issue to     leak memory from the vmx process. (CVE-2025-22226)

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