Windows 10 (Version 1809 LTSC) patch distribution schedule.

Hi,

Question 1.

The following vulnerabilities were found in Windows10 (“Version 1809 LTSC”). However, I cannot see the patch information that has been deployed.

(I want to emphasize that it is about Version 1809 LTSC)

Is the reason patch for the vulnerabilities below have not been deployed because vulnerabilities are not related to Windows10 “Version 1809 LTSC”?
