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: mm/mempolicy: skip non-present PMDs     when queueing folios Patch series mm: handle device-private PMDs in walk callbacks, v3. Since commit     368076f52ebe (mm/huge_memory: add device-private THP support to PMD operations) a PMD may hold a device-     private swap entry whenever an HMM-based GPU driver migrates an anonymous THP folio to device memory via     migrate_vma_pages(). pmd_trans_huge_lock() succeeds for such PMDs (pmd_is_huge() returns true for any non-     present, non-none huge PMD), so several MM walk callbacks that used to assume present THP or migration     entry are now reachable with a device-private PMD. The results range from a VM_BUG_ON() firing on debug     kernels, to an oops on a bogus vmemmap dereference, to silently isolating an unrelated live folio from LRU     in the aliasing case. This patch (of 3): queue_folios_pmd() is called under pmd_trans_huge_lock(), whose     pmd_is_huge() check returns true for any non-present, non-none PMD softleaf. Passing such a PMD to     pmd_folio() treats the softleaf encoding as a hardware PFN and can return a bogus folio pointer. Mirror     queue_folios_pte_range(): handle non-present entries before looking up a folio. Keep migration entries     counted as failures, but skip other non-present PMDs such as device-private entries. Potential trigger: an     HMM-based GPU driver migrates an anonymous THP folio to device memory via migrate_vma_pages(), leaving a     device-private PMD. Userspace then calls mbind(), migrate_pages() or set_mempolicy_home_node() on that     range. (CVE-2026-89758)

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