Spectre v2 vulnerability

Recommended Posts

Looking at lscpu reports turns out that my board is vulnerable to spectre v2 because eBPF is enabled. I tryed to disable it by using sysctl but it seems it doesn't work (this is the solution used by ubuntu distributions to solve the problem 'sudo sysctl kernel.unprivileged_bpf_disabled=1 or 2').

 

I'm on Debian version. Is this option kernel dependent?
