which version(build) included the meltdown/spectre mitigation?

i mean the CVE-2017-5754, CVE-2017-5753 and CVE-2017-5715 vulnerabilities of CPU.

does the ESXi 6.5 U1g build 7967591 include the 3 mitigation update patches?

and is it the oldest ESXi version which has the 3 mitigations?

or there's other ESXi patches versions which could update the meltdodwn/spectre issue earlier then 6.5U1g?

what about ESXi 6.7?
