Subject: [PATCH 3.13 208/259] qlcnic: info leak in qlcnic_dcb_peer_app_info()
3.13.11.6 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@...cle.com>
[ Upstream commit 7df566bbdd0af0785542b89466a937e94257fcfb ]
This function is called from dcbnl_build_peer_app(). The "info"
struct isn't initialized at all so we disclose 2 bytes of uninitialized
stack data. We should clear it before passing it to the user.
Fixes: 48365e485275 ('qlcnic: dcb: Add support for CEE Netlink interface.')
