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

  - In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Disable preemption when     probing user return MSRs Disable preemption when probing a user return MSR via RDSMR/WRMSR. If the MSR     holds a different value per logical CPU, the WRMSR could corrupt the host's value if KVM is preempted     between the RDMSR and WRMSR, and then rescheduled on a different CPU. Opportunistically land the helper in     common x86, SVM will use the helper in a future commit. (CVE-2021-46977)

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