CVE-2018-16658  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade torvalds/linux to version 4.18.6 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940.
