The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-005648 advisory.

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

    riscv: process: fix kernel info leakage

    thread_struct's s[12] may contain random kernel memory content, which     may be finally leaked to userspace. This is a security hole. Fix it     by clearing the s[12] array in thread_struct when fork.

    As for kthread case, it's better to clear the s[12] array as well.

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.
