Which bug was able to trigger with non-root? The hash one that you
reported? That is something with the function tracer. Are you able to
enable function tracing as non-root?

Or is it because you gave more permissions for non-root to use extra
perf commands. Because no one but root should be able to enable
function tracing, as that can add a large overhead to the system.
