-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 0xd08
-
- Hardware check
