RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:

2.Switch to tty login UI.
3.Input Up and Down keys there.
Actual results:

Expected results:
The Up and Down keys should not working here.
Additional info:
Sorry I really don't know which component should I pickup, I was trying to select the "plymouth" but it seems like the GUI .
This is a well-known issue (for 20+ years). I have doubts it's possible to fix it in some elegant way that will not affect some corner cases.
The problem is that system (usually agetty) has no clue about the current terminal setting, so it tries to minimize a way how to interpret the input. Now it supports only erase (erase one char) and kill (erase all input) keys; everything else is interpreted as username. Later after login, the session is fully configured, and it's possible to work with arrow and Fn keys.
Anyway, this has to be done upstream and tested before it will be in RHEL. It's already discussed upstream: https://github.com/util-linux/util-linux/issues/2068
