What I think there is an error ok KB and version should be:
| vCenter Appliance 6.7 Update 3p (6.7.0.51000) | 2021-11-23 | 18831133 | 18831049 |
| vCenter Appliance 6.7 Update 3o (6.7.0.50000) | 2021-09-21 | 18485166 | 18485185 |
Or just go for the newest one:
| vCenter Appliance 6.7 Update 3r (6.7.0.53000) | 2022-07-12 | 19832974 | 19832280 |
