The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3840 advisory.
hw: Machine Check Error on Page Size Change (IFU) (CVE-2018-12207)
hw: Intel GPU Denial Of Service while accessing MMIO in lower power state (CVE-2019-0154)
hw: TSX Transaction Asynchronous Abort (TAA) (CVE-2019-11135)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
