概要
netfilter: nf_tables: don't unregister hook when table is dormant
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: don't unregister hook when table is dormant
When nf_tables_updchain encounters an error, hook registration needs to
be rolled back.
This should only be done if the hook has been registered, which won't
happen when the table is flagged as dormant (inactive).
Just move the assignment into the registration block.
