SMB share is writable via NFS protocol and therefore susceptible to CVE 2021-20316

I upgraded to 12.0-8 and once it rebooted, I am getting a number of the below error messages.
SMB share is writable via NFS protocol and therefore susceptible to CVE 2021-20316.

I use a combination of Linux and Windows clients, so the home directories are mapped with nfs and smb as the login can be from either client.

What do i have to do to fix?​
