It's "overblown" because of these dumb CVSS scores that get attached to vulnerabilities as if they had any meaning at all (they do not). By itself, it's just a marginally interesting semi-remote vuln, effectively a privesc within a K8s deployment.
Heartbleed was a 7.5. The entire security community is constantly shouting "RED ALERT, THIS IS A MUCH MUCH WORSE VULNERABILITY THAN HEARTBLEED" and they're all just non-issues.
