Probably more or less this:

$ uname -a; id -u; dmesg | sed 1q
Linux mouchine 5.15.0-86-generic #96-Ubuntu SMP Wed Sep 20 08:23:49 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
1001
dmesg: read kernel buffer failed: Operation not permitted
$ 

I'm not Linux expert enough to more than guess at why the difference.
