"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-003617 advisory.

    An information disclosure vulnerability exists when certain central processing units (CPU) speculatively
    access memory. An attacker who successfully exploited the vulnerability could read privileged data across
    trust boundaries.
    To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially
    crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it
    could be used to obtain information that could be used to try to compromise the affected system further.
    On January 3, 2018, Microsoft released an advisory and security updatesrelated to a newly-discovered
    class of hardware vulnerabilities (known as Spectre) involving speculative execution side channels that
    affect AMD, ARM, and Intel CPUs to varying degrees. This vulnerability, released on August 6, 2019, is a
    variant of the Spectre Variant 1 speculative execution side channel vulnerability and has been assigned
    CVE-2019-1125.
    Microsoft released a security update on July 9, 2019 that addresses the vulnerability through a software
    change that mitigates how the CPU speculatively accesses memory. Note that this vulnerability does not
    require a microcode update from your device OEM.


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.");
