This bug in the kernel was patched in RHEL on 7/20. Every other mainstream Linux distro patched it that day or the day after. That includes Rocky and Alma. https://access.redhat.com/security/cve/CVE-2021-33909 It's still not patched six days later in CentOS Stream 8. This Bugzilla entry makes it clear that when it comes to security, CentOS Stream falls behind RHEL. But this far behind? https://bugzilla.redhat.com/show_bug.cgi?id=1975182 This doesn't make a good argument for Stream being a viable CentOS Linux replacement.
