I would like to inquire about the scope of security support for Rocky Linux 8.6 and 8.7. Does the security support include fixing security-related bugs and addressing bugs that occur in the operating system? Additionally, could you please share any documents or official website links where the scope of the security support is detailed?
Every six months Red Hat releases new point update for RHEL. That is new features.
After such release, and up to next point update for that major version, RHEL gets security fixes.
RHEL 8 has now released its last point update (8.10) and is in Maintenance Phase (the long dark blue bar) to 2029. That is, critical security (and bug) fixes may be released for it.
Rocky can access source code of at most what is released within the dark blue. The light blue (EUS) and green(?) have never been accessible. Hence Rocky cannot support old point updates.
