CVE-2018-1118
2.3 · LOWOverview
CVE-2018-1118 is a low-severity vulnerability affecting linux linux_kernel. It was published on May 10, 2018 and has a CVSS 3.0 base score of 2.3 (LOW).
This vulnerability has a CVSS 3.0 base score of 2.3, rated LOW. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
Linux kernel vhost since version 4.8 does not properly initialize memory in messages passed between virtual guests and the host operating system in the vhost/vhost.c:vhost_new_msg() function. This can allow local privileged users to read some kernel memory contents when reading from the /dev/vhost-net device file.
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.
