CrowdStrike Releases Fix for Updates Causing Windows to Enter BSOD Loop

CrowdStrike reported that a faulty Falcon Sensor Windows content update (channel file C-00000291*.sys, 0409 UTC) caused widespread BSODs across sectors including banking, airlines, and retail, while Mac and Linux were unaffected; the issue was not a security incident. The vendor quickly reverted the change, deployed a fixed update at 0527 UTC, and provided mitigation guidance (Safe Mode/WinRE file removal and cloud volume workflows), noting unaffected systems require no action and highlighting the need for staged, well-tested security software updates.
