Subject: Re: [PATCH 5.10.y] netfilter: nf_tables: make nft_object rhltable per table
Date: Sun, 6 Sep 2026 09:32:57 -0400 [thread overview]
Message-ID: <2026-09-05-daily-reply-0027-nf-tables-rhltable-5-10@kernel.org> (raw)
In-Reply-To: <20260904013055.22116-1-surajjs@amazon.com>
> The nft_object rhltable is global, this allows for accessing objects

> Given the nft_obj_destroy() releases the object inmediately, this might
> lead to use-after-free of these objects that are being released.
> Make the existing rhltable per table to address this issue to deal with
Queued for 5.10, thanks.
