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

  - KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry     vgic_its_invalidate_cache() walks the per-ITS translation cache with xa_for_each() and drops the cache's     reference on each entry with vgic_put_irq(). It puts the iterated pointer, though, rather than the value     returned by xa_erase(). The function is called from contexts that do not exclude one another: the ITS     command handlers hold its_lock, the GITS_CTLR write path holds cmd_lock, and the path that clears     EnableLPIs in a redistributor's GICR_CTLR holds neither. Two or more of them can drain the same cache     concurrently, and if each one observes the same entry, erases it and then puts it, the single reference     the cache holds on that entry is dropped more than once. The entry can then be freed while an ITE still     maps it. xa_erase() is atomic and returns the previous entry, so put only the entry that this context     actually removed. The cache reference is then dropped exactly once per entry even when the invalidations     run concurrently, and the behavior is unchanged when only one context runs. (CVE-2026-46316)

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