January saw the annoucement of a series of critical vulnerabilities called Spectre and Meltdown. The nature of these issues meant the solutions were complex and required fixing delicate code. The initial fix for Meltdown on x86 was KPTI, which was available almost immediately. Developing mitigations for Spectre was more complex. Other architectures had to look at their vulnerability status as well, and get mitigation in where it was needed. As a bit of time has passed, what is the exposure on Fedora now?
Meltdown and Spectre mitigation coverage
The mitigation coverage for Spectre and Meltdown is in a pretty good
