In the Linux kernel, the following vulnerability has been resolved:

mac802154: fix missing INITLISTHEAD in ieee802154ifadd()

Kernel fault injection test reports null-ptr-deref as follows:

BUG: kernel NULL pointer dereference, address: 0000000000000008 RIP: 0010:cfg802154netdevnotifiercall+0x120/0x310 include/linux/list.h:114 Call Trace: <TASK> rawnotifiercallchain+0x6d/0xa0 kernel/notifier.c:87 callnetdevicenotifiersinfo+0x6e/0xc0 net/core/dev.c:1944 unregisternetdevicemanynotify+0x60d/0xcb0 net/core/dev.c:1982 unregisternetdevicequeue+0x154/0x1a0 net/core/dev.c:10879 registernetdevice+0x9a8/0xb90 net/core/dev.c:10083 ieee802154ifadd+0x6ed/0x7e0 net/mac802154/iface.c:659 ieee802154registerhw+0x29c/0x330 net/mac802154/main.c:229 mcr20aprobe+0xaaa/0xcb1 drivers/net/ieee802154/mcr20a.c:1316

ieee802154ifadd() allocates wpandev as netdev's private data, but not init the list in struct wpandev. cfg802154netdevnotifier_call() manage the list when device register/unregister, and may lead to null-ptr-deref.

Use INITLISTHEAD() on it to initialize it correctly.
