I have installed Sparky kernel 6.8.3-sparky8-amd64.
I have got 8 × Intel® Core™ i5-10400F CPU @ 2.90GHz processor.
There is an info about Spectre 2 vulnerability - Vulnerable eIBRS with unprivileged eBPF.

I have disable it using this command
$ sudo sysctl kernel.unprivileged_bpf_disabled=0
but after restart it stills persist.

When I use linux-image-6.6.15-amd64 kernel there is no info like this above.
How to fix it?

Improved kernel 6.8.4 only so far, so test it and let me know does it help, please.

Thank you. It has helped.
Kernel 6.8.4-sparky8-amd64 is improved.

Cool, so other sparky's kernels: 5.15, 6.1 and 6.6 will be fixed on next versions.

I have noticed that my info About System shows only 8 × Intel® Core™ i5-10400F CPU @ 2.90GHz processor now. This is on kernel 6.8.4. My system monitor widget do not show ssd disks' temperature.

When I use 6.6.15 kernel widget shows these sensors and info About System shows 12 × Intel® Core™ i5-10400F CPU @ 2.90GHz processor.

This is strange but it is for another topic.
