Subject: [PATCH 5.4 15/92] serial: serial_core: Perform NULL checks for break_ctl ops
Date: Wed, 11 Dec 2019 16:05:06 +0100 [thread overview]
Message-ID: <20191211150225.739461664@linuxfoundation.org> (raw)
In-Reply-To: <20191211150221.977775294@linuxfoundation.org>
From: Jiangfeng Xiao <xiaojiangfeng@huawei.com>
commit 7d73170e1c282576419f8b50a771f1fcd2b81a94 upstream.
Doing fuzz test on sbsa uart device, causes a kernel crash
due to NULL pointer dereference:
