Vulnerability CVE-2024-44986
Published: 2024-09-04

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.
