NVD Description
Note: Versions mentioned in the description apply only to the upstream kubectl package and not the kubectl package as distributed by Oracle.
See How to fix? for Oracle:8 relevant fixed versions and status.
Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT() in newer versions and corrupts memory on earlier versions. continueDecoding() shouldn’t ever be called from filters after a local reply has been sent. Users are advised to upgrade. There are no known workarounds for this issue.
