Chapter 2. Viewing security advisories
This chapter describes where you can find information about Red Hat Security Advisories (RHSA) and how to display the advisories.
2.1. Displaying advisories on the Customer Portal
Red Hat publishes security advisories on the Red Hat Customer Portal. This section describes where you find the advisories, and how to filter and display them.
Open https://access.redhat.com/security/security-updates/ in a browser.
This page lists all security advisories Red Hat published.
Optionally, filter for a specific product, variant, version, and architecture. For example, to display only advisories for Red Hat Enterprise Linux 8, set the following filters:

Alternatively, select a minor version, such as 8.2.
