Title:	Missing Linux Kernel mitigations for 'GDS - Gather Data Sampling' hardware vulnerability (Downfall, INTEL-SA-00828)
Summary:	The remote host is missing one or more known mitigation(s) on; Linux Kernel side for the referenced 'GDS - Gather Data Sampling' hardware vulnerability dubbed; 'Downfall'.
Description:	Summary: The remote host is missing one or more known mitigation(s) on Linux Kernel side for the referenced 'GDS - Gather Data Sampling' hardware vulnerability dubbed 'Downfall'. Affected Software/OS: Various Intel CPUs. Please see the references for the full list of affected CPUs. Solution: The following solutions exist: - Update to a more recent Linux Kernel to receive mitigations on Kernel level and info about the mitigation status from it - Enable the mitigation(s) in the Linux Kernel (might be disabled depending on the configuration) Additional possible mitigations (if provided by the vendor) are to: - install a Microcode update - update the BIOS of the Mainboard Note: Please create an override for this result if one of the following applies: - the sysfs file is not available but other mitigations like a Microcode update is already in place - the sysfs file is not available but the CPU of the host is not affected - the reporting of the Linux Kernel is not correct (this is out of the control of this VT) CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:N/A:N
