Subject: [PATCH 4.9 15/32] USB: serial: mos7840: fix status-register error handling
Date: Mon, 16 Jul 2018 09:36:23 +0200 [thread overview]
Message-ID: <20180716073506.246221923@linuxfoundation.org> (raw)
In-Reply-To: <20180716073504.433996952@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 794744abfffef8b1f3c0c8a4896177d6d13d653d upstream.
Add missing transfer-length sanity check to the status-register
completion handler to avoid leaking bits of uninitialised slab data to
user space.
Fixes: 3f5429746d91 ("USB: Moschip 7840 USB-Serial Driver")
Cc: stable <stable@vger.kernel.org> # 2.6.19
