Is there any path where `skb` is allocated inside the kernel (e.g. by `nlmsg_new` or `alloc_skb`), and `skb->cb` is zeroed, but then `skb->cb` is overwritten by something else, and then passed to `netlink_recvmsg`? Or maybe `skb` is cloned, and `skb->cb` is not copied correctly? Or maybe `netlink_recvmsg` is receiving an `skb` that was NOT allocated for netlink, but for some other protocol, and then injected into a netlink socket? Wait, `udevd` is receiving a netlink message. `udevd` listens on netlink sockets (kobject uevent). Kobject uevents are generated by the kernel. Let's check how kobject uevents are generated and sent. Look at `lib/kobject_uevent.c`.]
