FEDORA-2018-44f8a7454d created by berrange 5 years ago for Fedora 28

New CPU features for speculative store bypass (CVE-2018-3639)

On Intel x86 hosts, the "ssbd" feature must be explicitly added to any virtual machines that are not using host-passthrough/host-model CPU setup. NB this requires new microcode too, which is not yet available in Fedora microcode_ctl RPMs.

On AMD x86 hosts, the "virt-ssbd" feature must be explicitly added to any virtual machines that are not using host-passthrough/host-model CPU setup. There is no microcode dependency for AMD as this is a virtualized CPUID feature.

In both cases, kernel >= 4.16.10-301 is required on the host and guest in order to activate the fix.
