How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream cilium-fips-1.20 package and not the cilium-fips-1.20 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector as a result.
