Subject: Re: [PATCH net] vsock: account only unread bytes in read_skb()
Date: Thu,  1 Oct 2026 23:32:21 +0900	[thread overview]
Message-ID: <20261001143221.3856511-1-4ncienth@gmail.com> (raw)
In-Reply-To: <179085716831.31693.13222203434770065965@kernel.org>

Thanks. I found this during an LLM-assisted manual source audit of VSOCK
receive accounting while re-evaluating virtio_transport_read_skb() after
CVE-2024-50169. I then confirmed it on vulnerable and fixed kernels using a
connected CID_LOCAL stream and a real SK_SKB/SOCKMAP verdict path.

Thanks,
Daehyeon
