CVE-2018-16658
6.1 · MEDIUMOverview
CVE-2018-16658 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 7, 2018 and has a CVSS 3.0 base score of 6.1 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 6.1, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
