Red Hat Enterprise Linux

How Red Hat Enterprise Linux versioning, EOL & security support work
RHEL major and minor versions (expressed as major.minor, such as 10.2) each move through a defined, multi-phase lifecycle set out in Red Hat's update and errata policy. Red Hat issues errata (RHSA for security, RHBA for bug fixes, RHEA for enhancements) applied cumulatively to the latest release, and minor releases periodically refresh hardware enablement and installation media.
Red Hat handles vulnerabilities through its own security response process, publishing RHSA errata for issues meeting defined severity criteria. Once a RHEL version reaches the Extended Life Phase, no further bug or security fixes are produced for it, so continuing to run it leaves systems exposed to unpatched vulnerabilities unless it's on an add-on extended-support subscription.
