The reson is that the lack\nof FILE will cause strlen to trigger NULL pointer dereference.\nThe corresponding stacktrace is shown below:\n\ndo_pin\n  do_pin_any\n    do_pin_fd\n      mount_bpffs_for_pin\n        strlen(name) <- NULL pointer dereference\n\nFix it by adding validation to the common process.",
