The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - KVM: x86: wean fast IN from emulator_pio_in Use __emulator_pio_in() directly for fast PIO instead of     bouncing through emulator_pio_in() now that __emulator_pio_in() fills val when handling in-kernel PIO.
    vcpu->arch.pio.count is guaranteed to be '0', so this a pure nop. emulator_pio_in_emulated is now the last     caller of emulator_pio_in. No functional change intended. (CVE-2022-4994)

Note that Nessus relies on the presence of the package as reported by the vendor.
