How did the update get through testing, if the bug has an immediately obvious catastrophic effect?
Agreed, this seems like a pretty obvious failed smoke test.
Three options seem likely to me: the build was untested, the final package got corrupted after testing, the test environment has some kind of abberant config that hid the defect.
Kernel drivers are "reviewed" and signed by Microsoft for exactly this reason. It's a security risk if any program an administrator runs could load malicious kernel drivers into windows
Something I have heard (take with a grain of salt) is that there was a new windows update that went out just before the crowdstrike update. And the issue happened with the new windows update.
Not the case. I have dozens of servers last updated in May that crashed.
