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

phonet: fix rtmphonetnotify() skb allocation

fillroute() stores three components in the skb:

- struct rtmsg - RTADST (u8) - RTAOIF (u32)

Therefore, rtmphonetnotify() should use

NLMSGALIGN(sizeof(struct rtmsg)) + nlatotalsize(1) + nlatotalsize(4)
