CrowdStrike Update Pushing Windows Machines Into a BSOD Loop

On July 19, 2024, a faulty CrowdStrike Falcon sensor update triggered widespread Windows 10/11 BSOD loops (“DRIVER_OVERRAN_STACK_BUFFER”), disrupting services globally across airlines, airports, banks, healthcare, media, and more; Microsoft noted service degradation while CrowdStrike identified and isolated the issue and released a fix, emphasizing it was not a cyberattack, with interim guidance to boot into Safe Mode and remove the C-00000291*.sys driver before normal boot.
