The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-013684 advisory.

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

    bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem

    The vmemmap pages is marked by kmemleak when allocated from memblock.
    Remove it from kmemleak when freeing the page.  Otherwise, when we reuse     the page, kmemleak may report such an error and then stop working.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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