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

  - KVM: arm64: nv: Write ESR_EL2 for injected nested SError exceptions kvm_inject_el2_exception() writes     ESR_EL2 for synchronous exceptions but not for SError. enter_exception64() does not write ESR_ELx for any     exception type, so the constructed syndrome is dropped. A guest L2 hypervisor taking a nested SError     observes stale ESR_EL2. This affects both kvm_inject_nested_serror() and the EASE path in     kvm_inject_nested_sea(). Write ESR_EL2 for except_type_serror, matching except_type_sync. (CVE-2026-80873)

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