This is a general vulnerability existing in specific CPUs (with Spectre V2). To mitigate this, you can disable eBPF for unprivileged users by doing the following:

Login to the Service Gateway using root or sgowner account.

Run the command:

sudo sysctl kernel.unprivileged_bpf_disabled=1

To verify the result, run the command:

cat /proc/sys/kernel/unprivileged_bpf_disabled

The result should be 1.
