Description
In the Linux kernel, the following vulnerability has been resolved:
mac802154: fix missing INIT_LIST_HEAD in ieee802154_if_add()
Kernel fault injection test reports null-ptr-deref as follows:
BUG: kernel NULL pointer dereference, address: 0000000000000008
RIP: 0010:cfg802154_netdev_notifier_call+0x120/0x310 include/linux/list.h:114

ieee802154_if_add() allocates wpan_dev as netdev's private data, but not
init the list in struct wpan_dev. cfg802154_netdev_notifier_call() manage
the list when device register/unregister, and may lead to null-ptr-deref.
Use INIT_LIST_HEAD() on it to initialize it correctly.
