cdrom: Fix info leak/OOB read in cdrom_ioctl_drive_status
Like d88b6d04 : "cdrom: information leak in cdrom_ioctl_media_changed()" There is another cast from unsigned long to int which causes a bounds check to fail with specially crafted input. The value is then used as an index in the slot array in cdrom_slot_status(). Signed-off-by:Scott Bauer <scott.bauer@intel.com> Signed-off-by:
