Thank you for your reply. I have already gone through this article, but I would like to know why I am getting these errors.
Reason I am asking, I have tested this patch in test environment only. I saw discovery report after installation of patch, It is updated to latest version and all SQL services working fine.
But if we deploy this patch in production environment is there any possibility to get any issue. Please clarify.
FYI:
I have tested CVE-2017-1856 patch on SQL 2012 SP3, there is no such error in event viewer. According to this the error is getting because of MS16-136(QFE) exist on the machine.
