Hello,
I, hereby, am submitting a 'system' package to the official SUSE repos as it is a program fairly well known and used in other Linux distributions such as Debian, Ubuntu, Fedora and Arch . . .
It is a "better" more detailed companion/alternative to `needs-restarting` program integrated in Zypper.

Please consider adding it because it is a handy program for checking anything system up-to-date related.

I tested the installed package on SUSE Leap 15.5 and it seems to be working fine without any hassles - not extensively though . . .

But the outputs are clear & clean:

`root@Nvisen-MU02--SUSE-LEAP-SERVER ~# needrestart
Scanning processes...
Scanning processor microcode...
Scanning linux images...

Pending kernel upgrade!

Running kernel version:
6.5.5-lp154.3.g6cf5261-default

Diagnostics:
The currently running kernel version is not the expected kernel version 6.6.0-rc3-lp155.1.g15b4ad8-default.

Restarting the system to load the new kernel will not be handled automatically, so you should consider rebooting. [Return]

The processor microcode seems to be up-to-date.

No services need to be restarted.

No containers need to be restarted.

No user sessions are running outdated binaries.

No VM guests are running outdated hypervisor (qemu) binaries on this host.`
.

Thanks for taking it into consideration,
Martin from Liberec
