After WMware was merged into Broadcom systems, it is very difficult to find VMware patches. Broadcom published this howto (because it is so non-intuitive).
These patches are located on support.broadcom.com. You will need to create an account, which can be done in a few minutes and at no cost.
Log in and choose “VMware Cloud Foundation” from the drop down menu near the top right.
Choose “My Downloads” from the menu on the left.
Choose “VMware vSphere” as the product (page two of the list).
Choose the “Solutions” tab.
Choose the edition and version of vSphere.
