From 60395bb60e0b5e4e0808ac8eb07a92f6c9cdea1f Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Mon, 23 Jul 2007 14:51:05 +0100 Subject: [PATCH] [SCSI] aacraid: Fix security hole On the SCSI layer ioctl path there is no implicit permissions check for ioctls (and indeed other drivers implement unprivileged ioctls). aacraid however allows all sorts of very admin only things to be done so should check.
