+Spectre and Meltdown Checks
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Following section displays the output of a running shell script to tell if
+system is vulnerable against the several speculative execution CVEs that were
+made public in 2018. Script is available on `Spectre & Meltdown Checker Github
+<https://github.com/speed47/spectre-meltdown-checker>`_.
