Date: Wed, 1 Jun 2016 12:11:16 -0400 From: Kangjie Lu <kangjielu@...il.com> To: santosh.shilimkar@...cle.com Cc: davem@...emloft.net, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, taesoo@...ech.edu, csong84@...ech.edu, Kangjie Lu <kjlu@...ech.edu> Subject: [PATCH] net: fix potential infoleak in rds_inc_info_copy The last field "flags" of object "minfo" is not initialized. Copying this object out may leak kernel stack data. Assign 0 to it to avoid leak.
