CrowdStrike explained that the file is not a kernel driver but is responsible for “how Falcon evaluates named pipe1 execution on Windows systems.” Security researcher and Objective See founder Patrick Wardle says that the explanation aligns with the earlier analysis he and others provided about the cause of the crash, as the problem file “C-00000291- “triggered a logic error that resulted in an OS crash” (via CSAgent.sys).”

Faulting inst: mov r9d, [r8]
R8: unmapped address
...taken from an array of pointers (held in RAX), index RDX (0x14 * 0x8) holds the invalid memory address@_JohnHammond pic.twitter.com/oqlAVwSlJj
