Summary

In the Linux kernel, in the netfilter/ipset module, kfree_rcu() was called before rcu_assign_pointer() when handling the comment extension, which is incorrect order. The order was fixed so that rcu_assign_pointer() is called first.

Risk Assessment

Incorrect order can lead to races and potential use-after-free.

Recommendation

Apply the Linux kernel patch that changes the order of kfree_rcu() and rcu_assign_pointer() in the ipset module.
