HighCVSS 7.8/10Last modified Sep 29, 2026

Description

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

ipv6: fix possible UAF in ip6_finish_output2()

If skb_expand_head() returns NULL, skb has been freed and associated dst/idev could also have been freed.

We need to hold rcu_read_lock() to make sure the dst and associated idev are alive.
