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:
grub2 uses a shell function called version_find_latest() to find the latest RHEL kernel. However sometimes it fails to identify the latest kernel resulting in an older kernel be booted instead of the latest one.

Version-Release number of selected component (if applicable):
grub2-tools-2.02-0.16.el7.x86_64


How reproducible:
always

Steps to Reproduce:
1. source /usr/share/grub/grub-mkconfig_lib  # get shell functions
2. version_find_latest /boot/vmlinuz-3.10.0-229.el7.x86_64 /boot/vmlinuz-3.10.0-229.11.1.el7.x86_64


Actual results:
/boot/vmlinuz-3.10.0-229.el7.x86_64

Expected results:
It should output the latest release, which is:
/boot/vmlinuz-3.10.0-229.11.1.el7.x86_64

Additional info:

I believe this is being addressed in BZ #1124074 and the fix is coming soon.
