Subject: [Patch] Array overrun in drivers/net/tokenring/3c359.c
Date: Wed, 21 Jun 2006 16:33:58 +0200	[thread overview]
Message-ID: <1150900438.20915.6.camel@alice> (raw)

hi,

this was spotted by coverity (#id 502)
the xl_laa[] array has only 6 entries, since the else
case uses i-10 as array index to dev->dev_addr[] i guess
thats what should be done here too
