Remedy

This flaw can be mitigated by disabling unprivileged user namespaces will prevent exploitation: ~~~ sysctl -w kernel.unprivileged_userns_clone = 0 ~~~

Remedy

If not needed, disable the ability for unprivileged users to create namespaces. To do this temporarily, do: sudo sysctl -w kernel.unprivileged_userns_clone=0 To disable across reboots, do: echo kernel.unprivileged_userns_clone=0 | \ sudo tee /etc/sysctl.d/99-disable-unpriv-userns.conf
