Can someone please give some pointers.
Adding some more details, the module name is "npdereference.ko" and the function
where the crash is done looks like below. So I expect "null_deref_module_init"
to be present instead of "_MODULE_INIT_TEXT_START_npdereference" :
static int __init null_deref_module_init(void) {
// Pointer to an integer, initialized to NULL
int *null_pointer = NULL;
printk(KERN_INFO "Null dereference module loaded\n");
// Dereferencing the NULL pointer to trigger a crash
printk(KERN_INFO "Triggering null pointer dereference...\n");
*null_pointer = 1; // This line will cause a null pointer dereference
return 0; // This will never be reached
}
