jm + meltdown + hardware   1

Notes from the Intelpocalypse [LWN.net]
What emerges is a picture of unintended processor functionality that can be exploited to leak arbitrary information from the kernel, and perhaps from other guests in a virtualized setting. If these vulnerabilities are already known to some attackers, they could have been using them to attack cloud providers for some time now. It seems fair to say that this is one of the most severe vulnerabilities to surface in some time.

The fact that it is based in hardware makes things significantly worse. We will all be paying the performance penalties associated with working around these problems for the indefinite future. For the owners of vast numbers of systems that cannot be updated, the consequences will be worse: they will remain vulnerable to a set of vulnerabilities with known exploits. This is not a happy time for the computing industry.
