Subject: [patch] aacraid: information leak in aac_send_raw_srb()
Date: Tue, 07 Feb 2017 15:00:00 +0000 [thread overview]
Message-ID: <20170207150000.GA1757@mwanda> (raw)
The aac_srb_reply struct ends in a 2 byte hole so we end up leaking a
bit of information to user space.
Fixes: 423400e64d37 ("scsi: aacraid: Include HBA direct interface")
