| Subject: cpqarray: fix info leak in ida_locked_ioctl() |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| commit 627aad1c01da6f881e7f98d71fd928ca0c316b1a upstream. |
| |
| The pciinfo struct has a two byte hole after ->dev_fn so stack |
| information could be leaked to the user. |
| |
| This was assigned CVE-2013-2147. |
