The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001904 advisory.

    The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows     local users to cause a denial of service (memory corruption or system crash) by accessing certain memory     locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage     migration, related to fs/proc/task_mmu.c and mm/mempolicy.c.

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.
