+Description:   Information about CPU vulnerabilities
+
+               The files are named after the code names of CPU
+               vulnerabilities. The output of those files reflects the
+               state of the CPUs in the system. Possible output values:
+
+               "Not affected"    CPU is not affected by the vulnerability
+               "Vulnerable"      CPU is affected and no mitigation in effect
+               "Mitigation: $M"  CPU is affetcted and mitigation $M is in effect
