  • How do I protect myself?
  • Is the KPTI/KAISER patch sufficient to protect my computer?
  • The patch is claimed to induce a loss of performance; is it true? How much does this mean?
  • Can/should I disable the new patch if I'm worried about performance losses? What are the risks?
  • Which platforms and CPUs are vulnerable?
  • I'm running a virtual machine/containers; to what extent am I vulnerable?
  • Can I detect a Meltdown/Spectre attack on my computer?
  • Are these attacks remote code execution vulnerabilities?
