The Severity should be minor, apology for the input.

Hello and thanks for report.
It looks like an upstream distro issue: https://bugzilla.redhat.com/show_bug.cgi?id=1885823
We'll have to wait for update.

Fortunately, the previous version of dmidecode doesn't have this issue.
But we don't have it in AlmaLinux as we're new distribution so if you need to mitigate the issue right now you should install the previous version of dmidecode from other distro.

Here is example with CloudLinux 8.2 package I've tested:

# Downgrade to previous version
dnf downgrade https://repo.cloudlinux.com/cloudlinux/8.2/BaseOS/x86_64/os/Packages/dmidecode-3.2-5.el8.x86_64.rpm

# Install dnf versionlock plugin
dnf install 'dnf-command(versionlock)'

# Lock dmidecode to previous version until fixed package will be relesed
dnf versionlock add dmidecode

Yep right now this version is in CentOS Stream 8 only.
Most likely RHEL 8.5 will include it.
