Subject: [PATCH AUTOSEL 5.3 095/203] media: hdpvr: add terminating 0 at end of string
Date: Sun, 22 Sep 2019 14:42:01 -0400 [thread overview]
Message-ID: <20190922184350.30563-95-sashal@kernel.org> (raw)
In-Reply-To: <20190922184350.30563-1-sashal@kernel.org>
From: Hans Verkuil <hverkuil-cisco@xs4all.nl>
[ Upstream commit 8b8900b729e4f31f12ac1127bde137c775c327e6 ]
dev->usbc_buf was passed as argument for %s, but it was not safeguarded
by a terminating 0.
This caused this syzbot issue:
