Dereferencing NULL pointer - Visual Studio

Question

While using my code in Visual Studio, I got a warning of dereferencing NULL pointer at p[i] = (int)i;. Anybody knows how can I avoid this warning?

#define ARRAY_LEN   5

int main(void)
{
    int* p;
    p = (int*)malloc(ARRAY_LEN * sizeof(int));
    for (size_t i = 0; i < ARRAY_LEN; i++)
    {
        p[i] = (int)i;
    }
}
