However, in the unlikely\ncase that the error handler thread fails to spawn, shost->ehandler is set\nto ERR_PTR(-ENOMEM).\n\nThe error handler cleanup code in scsi_host_dev_release() will call\nkthread_stop() if shost->ehandler != NULL which will always be the case\nwhether the kthread was successfully spawned or not. In the case that it\nfailed to spawn this has the nasty side effect of trying to dereference an\ninvalid pointer when kthread_stop() is called. The following splat provides\nan example of this behavior in the wild:\n\nscsi host11: error handler thread failed to spawn, error = -4\nKernel attempted to read user page (10c) - exploit attempt?
