CVE-2015-5697  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.1.6 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. The get_bitmap_file function in drivers/md/md.c in the Linux kernel before 4.1.6 does not initialize a certain bitmap data structure, which allows local users to obtain sensitive information from kernel memory via a GET_BITMAP_FILE ioctl call.
