To understand what a Docker CVE is, you need to first know what is CVE. CVEs are actually a system that is maintained by the MITRE Corporation. These are used as a public way of providing information based on a CVE number that is dedicated to each vulnerability for easy reference. This allows a national database of all the vulnerabilities that are given a CVE number from the MITRE Corporation. To learn more about CVEs, you can find it on the Wikipedia article here:

https://en.wikipedia.org/wiki/Common_Vulnerabilities_and_Exposures

The Wikipedia article explains things such as how they go about giving CVE numbers and the format that they all follow.

Now that you know what CVEs are, you probably have already pieced together what Docker CVEs are. They are CVEs that are directly related to Docker security incidents or issues. To learn more about Docker CVEs or see a list of current Docker CVEs, visit https://www.docker.com/docker-cve-database.

This listing will be updated anytime a CVE is created for a Docker product. As you can see, the list is very small, therefore, this is probably a list that will not grow on a day-to-day, or even a month-to-month, basis frequency.
