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

  - hugetlbfs: don't delete error page from pagecache This change is very similar to the change that was made     for shmem [1], and it solves the same problem but for HugeTLBFS instead. Currently, when poison is found     in a HugeTLB page, the page is removed from the page cache. That means that attempting to map or read that     hugepage in the future will result in a new hugepage being allocated instead of notifying the user that     the page was poisoned. As [1] states, this is effectively memory corruption. The fix is to leave the page     in the page cache. If the user attempts to use a poisoned HugeTLB page with a syscall, the syscall will     fail with EIO, the same error code that shmem uses. For attempts to map the page, the thread will get a     BUS_MCEERR_AR SIGBUS. [1]: commit a76054266661 (mm: shmem: don't truncate page if memory failure     happens) (CVE-2022-49828)

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

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011186 advisory.

    In the Linux kernel, the following vulnerability has been resolved:
