Subject: [PATCH 03/10] ALSA: Limit the fallback card id string size
Date: Tue, 29 Oct 2013 17:00:26 +0100 [thread overview]
Message-ID: <1383062433-9388-4-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1383062433-9388-1-git-send-email-tiwai@suse.de>
When no proper id string is given, the driver tries to fall back to
copy the proc_root name string via strcpy(), but this might overflow
the fixed string size. Let's use strlcpy().
Spotted by coverity CID 139008.
