How to fix?

There is no fixed version for RHEL:8 netty-codec-http.

NVD Description

Note: Versions mentioned in the description apply only to the upstream netty-codec-http package and not the netty-codec-http package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAX_VALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYN_STREAM frames with FLAG_FIN=0, causing unbounded heap and direct memory allocation that can lead to JVM OutOfMemoryError and a denial of service.
