|
- Check the currently running kernel for Spectre or Meltdown:
|
|
|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker`
|
|
|
|
|
|

|
|
|
- Check the currently running kernel and show an explanation of the actions to take to mitigate a vulnerability:

|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker --explain`
|
|
|
|
|
|
|
|
|
|
- Check for specific variants (defaults to all):
|
|
|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker --variant {{1|2|3|3a|4|l1tf|msbds|mfbds|mlpds|mdsum|taa|mcespc|srbds}}`
|
|
|
|
|
|
|
|
|
|
- Display output using a specific output format:
|
|
|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker --batch {{text|json|nrpe|prometheus|short}}`
|
|
|
|
|
|
|
|
|
|
- Don't use the `/sys` interface even if present:
|
|
|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker --no-sysfs`
|
|
|
|
|
|
|
|
|
|
- Check a non-running kernel:
|
|
|
|
|
|
|
|
|
|
`sudo spectre-meltdown-checker --kernel {{path/to/kernel_file}}`
|
