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 Call Trace: <TASK> raw_notifier_call_chain+0x6d/0xa0 kernel/notifier.c:87 call_netdevice_notifiers_info+0x6e/0xc0 net/core/dev.c:1944 unregister_netdevice_many_notify+0x60d/0xcb0 net/core/dev.c:1982 unregister_netdevice_queue+0x154/0x1a0 net/core/dev.c:10879 register_netdevice+0x9a8/0xb90 net/core/dev.c:10083 ieee802154_if_add+0x6ed/0x7e0 net/mac802154/iface.c:659 ieee802154_register_hw+0x29c/0x330 net/mac802154/main.c:229 mcr20a_probe+0xaaa/0xcb1 drivers/net/ieee802154/mcr20a.c:1316
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.
