"The version of QEMU installed on the remote Windows host is prior to 8.2.1 and therefore vulnerable to the following:

  - An issue was discovered in QEMU 7.0.0 through 8.2.1. register_vfs in hw/pci/pcie_sriov.c does not set NumVFs to 
    PCI_SRIOV_TOTAL_VF, and thus interaction with hw/nvme/ctrl.c is mishandled.

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