Description Paul McKeith 2023-07-07 18:23:18 UTC 
Performing Kernel Live Patching:

https://documentation.suse.com/sles/15-SP3/html/SLES-all/cha-klp.html#sec-klp-perform

Please add information to the docs informing the admin that the output of the uname command will NOT change when live patching is used. Instead the klp command is to be used. This is often a confusion of customers new to live patching and security tools that scan servers only with the "uname -a" command to determine if a server has any outstanding CVEs that need to be applied.

Hi Tomas,
It is minor edit but you can change "uname -a" to "uname -r" or better just "uname". Also it would be best to have engineering review to see if anything else should be mentioned in this change. 

Note that below is an an article dedicated to live patching for RHEL that makes this point very clear. Of course for SLE it is similar but not exactly the same:

Thank you Tomáš! It is much clearer now.
