"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-001021 advisory.

    The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls
    have two different futex addresses, which allows local users to gain privileges via a crafted
    FUTEX_REQUEUE command that facilitates unsafe waiter modification.

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.");
