Subject: [PATCH AUTOSEL 5.15 11/28] tipc: fix a bit overflow in tipc_crypto_key_rcv()
Date: Tue, 22 Feb 2022 21:29:12 -0500 [thread overview]
Message-ID: <20220223022929.241127-11-sashal@kernel.org> (raw)
In-Reply-To: <20220223022929.241127-1-sashal@kernel.org>
From: Hangyu Hua <hbh25y@gmail.com>
[ Upstream commit 143de8d97d79316590475dc2a84513c63c863ddf ]
msg_data_sz return a 32bit value, but size is 16bit. This may lead to a
bit overflow.
