The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-004022 advisory.

    In the Linux kernel 5.5.0 and newer, the bpf verifier (kernel/bpf/verifier.c) did not properly restrict     the register bounds for 32-bit operations, leading to out-of-bounds reads and writes in kernel memory. The     vulnerability also affects the Linux 5.4 stable series, starting with v5.4.7, as the introducing commit     was backported to that branch. This vulnerability was fixed in 5.6.1, 5.5.14, and 5.4.29. (issue is aka     ZDI-CAN-10780)

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.
