+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>`_.
+
+::
+
+ Spectre and Meltdown mitigation detection tool v0.45
+
+ Checking for vulnerabilities on current system
+ Kernel is Linux 5.15.0-46-generic #49-Ubuntu SMP Thu Aug 4 18:08:11 UTC 2022 aarch64
+ CPU is ARM v8 model 0xd0c
