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

  - A vulnerability was found in the Linux kernel's KVM subsystem in arch/x86/kvm/lapic.c kvm_free_lapic when     a failure allocation was detected. In this flaw the KVM subsystem may crash the kernel due to mishandling     of memory errors that happens during VCPU construction, which allows an attacker with special user     privilege to cause a denial of service. This flaw affects kernel versions prior to 5.15 rc7.
    (CVE-2021-4032)

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