is being tracked here:

Title:
  openssh-client encounters MAC algo issue with EL8

Status in openssh package in Ubuntu:
  Invalid

Bug description:
  Ubuntu 22.04 system connecting to an Oracle Linux v8 host.  The
  following error occurs regardless of the the MACs specified (or not)
  in sshd_config:

  Corrupted MAC on input.
  ssh_dispatch_run_fatal: Connection to XX.XX.XX.XX port 22: message authentication code incorrect

  Presumably, this may happen on any RHEL v8 variant. Note that
  connecting to Enterprise Linux v7 work as well as other Ubuntu hosts.
  Downgrading to previous version of openssh-client fixes issue.

  apt install openssh-client=1:8.9p1-3
