Only some of them: l1tf mds meltdown spec_store_bypass spectre_v1 spectre_v2 Wikipedia shows more variants: https://en.wikipedia.org/wiki/Meltdown_(security_vulnerability)#Speculative_execution_security_vulnerabilities It would be good to have a full list with statuses. Then one won't need to use external (potentially non-safe) tools like https://github.com/speed47/spectre-meltdown-checker to find out the vulnerabilities of a system. This started as a feature request on openSUSE's bugzilla where it was suggested to report it here: http://bugzilla.suse.com/show_bug.cgi?id=1145191
