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

  - mm/userfaultfd: fix hugetlb fault mutex hash calculation In mfill_atomic_hugetlb(), linear_page_index() is     used to calculate the page index for hugetlb_fault_mutex_hash(). However, linear_page_index() returns the     index in PAGE_SIZE units, while hugetlb_fault_mutex_hash() expects the index in huge page units. This     mismatch means that different addresses within the same huge page can produce different hash values,     leading to the use of different mutexes for the same huge page. This can cause races between faulting     threads, which can corrupt the reservation map and trigger the BUG_ON in resv_map_release(). Fix this by     introducing hugetlb_linear_page_index(), which returns the page index in huge page granularity, and using     it in place of linear_page_index(). (CVE-2026-31575)

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