The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001225 advisory.

    drivers/net/usb/catc.c in the Linux kernel 4.9.x before 4.9.11 interacts incorrectly with the     CONFIG_VMAP_STACK option, which allows local users to cause a denial of service (system crash or memory     corruption) or possibly have unspecified other impact by leveraging use of more than one virtual page for     a DMA scatterlist.

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.
