Subject: [PATCH 3.13 208/259] qlcnic: info leak in qlcnic_dcb_peer_app_info() -stable review patch.  If anyone has any objections, please let me know.


From: Dan Carpenter <>

[ 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.')
