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.

Vulnerability from github – Published: 2026-06-03 18:33 – Updated: 2026-06-03 18:33

Details

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.
