Upon creation of 3 – 5 nodes, segmentation fault is encountered. Why?

I am currently trying to create a phonebook with a linked list. I am focusing first on the insertion function but the problem is that once I create 3 – 5 nodes, onlineGDB shows the error "malloc : corrupted top size", and VS Code shows that I got a segmentation error.

I assume this is an error with the way I am allocating memory. This is the first time that I am working on a structure that contains strings as data instead of integer so I might have missed a thing or two.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

struct node{
    char name[30];
    char number[15];
    struct node *next;
};

void showMenu();
void insertData(struct node **head, char person[], char phone[]);
void showData(struct node *head);

int main(){

    struct node *head = NULL;
    char name[30], number[15];
    while(1)
    {
        printf("Name : ");
        scanf(" %[^\n]s", name);
        printf("Number: ");
        scanf(" %[^\n]s", number);
        insertData(&head, name, number);
        showData(head);
    }
    return 0;
}

void insertData(struct node **head, char person[], char phone[]){

    struct node *new_node = (struct node*) malloc(sizeof(struct node*));
    strcpy(new_node->name, person);
    strcpy(new_node->number, phone);
    new_node->next = *head;
    *head = new_node;
}

void showData(struct node *head){

    while(head != NULL)
    {
        printf("%s\t\t%s\n", head->name, head-> number);
        head = head->next;
    }    
    printf("\n");
}

>Solution :

Use malloc(sizeof(struct node)) instead of malloc(sizeof(struct node*)) in your function insertData(). You want to allocate the size of the node and not the pointer to node.
