Summary
In the Linux kernel, the following vulnerability has been resolved:
ila: call nf_unregister_net_hooks() sooner
syzbot found an use-after-free Read in ila_nf_input [1]
Issue here is that ila_xlat_exit_net() frees the rhashtable,
then call nf_unregister_net_hooks().
It should be done in the reverse way, with a synchronize_rcu().
This is a good match for a pre_exit() method.
