Subject: Re: [PATCH virt] virt: fix uninit-value in vhost_vsock_dev_open
Date: Sun, 21 Apr 2024 12:06:06 +0900 [thread overview]
Message-ID: <20240421030606.80385-1-aha310510@gmail.com> (raw)
In-Reply-To: <20240420060450-mutt-send-email-mst@kernel.org>
static bool vhost_transport_seqpacket_allow(u32 remote_cid)
{
....
vsock = vhost_vsock_get(remote_cid);
if (vsock)
seqpacket_allow = vsock->seqpacket_allow;
....
}
I think this is due to reading a previously created uninitialized
vsock->seqpacket_allow inside vhost_transport_seqpacket_allow(),
which is executed by the function pointer present in the if statement.
Thanks
