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: mshv: Fix infinite fault loop on     permission-denied GPA intercepts Prevent infinite fault loops when guests access memory regions without     proper permissions. Currently, mshv_handle_gpa_intercept() attempts to remap pages for all faults on     movable memory regions, regardless of whether the access type is permitted. When a guest writes to a read-     only region, the remap succeeds but the region remains read-only, causing immediate re-fault and spinning     the vCPU indefinitely. Validate intercept access type against region permissions before attempting remaps.
    Reject writes to non-writable regions and executes to non-executable regions early, returning false to let     the VMM handle the intercept appropriately. This also closes a potential DoS vector where malicious guests     could intentionally trigger these fault loops to consume host resources. (CVE-2026-43096)

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