How to fix?

This issue was patched in ELSA-2017-3516.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek package and not the kernel-uek package as distributed by Oracle. See How to fix? for Oracle:5 relevant fixed versions and status.

The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call.
