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

  - KVM: SVM: Add missing save/restore handling of LBR MSRs MSR_IA32_DEBUGCTLMSR and LBR MSRs are currently     not enumerated by KVM_GET_MSR_INDEX_LIST, and LBR MSRs cannot be set with KVM_SET_MSRS. So save/restore is     completely broken. Fix it by adding the MSRs to msrs_to_save_base, and allowing writes to LBR MSRs from     userspace only (as they are read-only MSRs) if LBR virtualization is enabled. Additionally, to correctly     restore L1's LBRs while L2 is running, make sure the LBRs are copied from the captured VMCB01 save area in     svm_copy_vmrun_state(). Note, for VMX, this also fixes a flaw where MSR_IA32_DEBUGCTLMSR isn't reported as     an MSR to save/restore. Note #2, over-reporting MSR_IA32_LASTxxx on Intel is ok, as KVM already handles     unsupported reads and writes thanks to commit b5e2fec0ebc3 (KVM: Ignore DEBUGCTL MSRs with no effect)     (kvm_do_msr_access() will morph the unsupported userspace write into a nop). [sean: guard with lbrv     checks, massage changelog] (CVE-2026-46014)

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