Microsoft’s Patch Tuesday included over 80 patches in total, including a vulnerability in Windows Defender that is already being exploited in the wild.

If you are missing this fix in your list, its possible that this bug has already been patched by Microsoft on end-user systems, as the company continuously updates Defender outside of the normal monthly patch cycle.”]
