Description Marco Benatto 2022-12-16 17:47:06 UTC 
The "RC4" protection of the NetLogon Secure channel uses the same algorithms as rc4-hmac cryptography in Kerberos, and so must also be assumed to be weak.

Doesn't this issue impact RHEL 8.6? If it does not, shouldn't the CVE page(https://access.redhat.com/security/cve/cve-2022-38023) explicitly state that? 

I have a customer who is complaining about this CVE in CoreOS 4.11.28 (shipped with their ARO cluster). CoreOS 4.11.28 is built with RHEL 8.6 EUS (https://access.redhat.com/articles/6907891)
