That's Meltdown, the Intel bug in memory isolation.
Spectre is a CPU cache timing attack to derive data. Cache lines are cleared in between context switches, so it can only affect the same process.
- monocasa 7y agoCache lines aren't cleared on context switches, and there are Spectre variants that are cross address space. There's even a remote Spectre exploit. https://arxiv.org/abs/1807.10535 https://arxiv.org/abs/1807.10535
- lucian1900 7y agoOh. I entirely misunderstood, then. I stand corrected.
