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

  - mshv: Fix error handling in mshv_region_pin The current error handling has two issues: First,     pin_user_pages_fast() can return a short pin count (less than requested but greater than zero) when it     cannot pin all requested pages. This is treated as success, leading to partially pinned regions being     used, which causes memory corruption. Second, when an error occurs mid-loop, already pinned pages from the     current batch are not properly accounted for before calling mshv_region_invalidate_pages(), causing a page     reference leak. Treat short pins as errors and fix partial batch accounting before cleanup.
    (CVE-2026-43045)

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