 After that, `nf_tables_destroy_set` function, which is eventually reached from `nf_tables_rule_destroy` [1], checks that the given set is an anonymous set and is not bind to anywhere [2]. If so, `nft_set_destroy` function frees this set [3].

-Unfortunately, this freed set object is still accessible in the following commands of the same transaction. This is because this object was not properly deactivated (i.e., `nft_activate_genmask` will return true). From this, we can see why the patch works; It doesn't unbind the set object but only deactivates it, making it non-accessible.
