Good catch by @TomSellers - although VMware doesn't list ESXi 6.7 as vulnerable, it is - they've published a patch for it: https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/6-7/release-notes/esxi-update-and-patch-release-notes/vmware-esxi-67-patch-release-esxi670202503001.html
I think what's happening here is 6.7 is under premium (paid) extended support where they publish patches for high severity vulns.
This also tends to indicate it applies to other unsupported versions. The forum post suggested that vuln worked on ESXi 5.x - no patch is available that far back.
I think this may be a big problem for many orgs.
