UTSA-2026-003534 advisory.

    Systems with microprocessors utilizing speculative execution and speculative execution of memory reads
    before the addresses of all prior memory writes are known may allow unauthorized disclosure of information
    to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB),
    Variant 4.

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
