> Multiple engineers identified the issue via analysis of stack dumps as being triggered by a null pointer bug in the C++ the Crowdstrike update was written in; it appears to have tried to call an invalid region of memory that results in a process getting immediately killed by Windows, but that take looked increasingly controversial and Crowdstrike itself said that the incident was not due to "null bytes contained within Channel File 291 [the update that triggered the crashes] or any other Channel File."
