Title
ipv6: Fix out-of-bound access in fib6_add_rt2node().
Summary
In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix out-of-bound access in fib6_add_rt2node(). syzbot reported out-of-bound read in fib6_add_rt2node(). [0] When IPv6 route is created with RTA_NH_ID, struct fib6_info does not have the trailing struct fib6_nh. The cited commit started to check !iter->fib6_nh->fib_nh_gw_family to ensure that rt6_qualify_for_ecmp() will return false for iter. If iter->nh is not NULL, rt6_qualify_for_ecmp() returns false anyway. Let's check iter->nh before reading iter->fib6_nh and avoid OOB read.
