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

netfilter: ipset: fix order of kfree_rcu() and rcu_assign_pointer()

Sashiko pointed out that kfree_rcu() was called before
rcu_assign_pointer() in handling the comment extension.
Fix the order so that rcu_assign_pointer() called first.
