Reading privileged memory with a side-channel (Meltdown & Spectre)

We have discovered that CPU data cache timing can be abused to efficiently leak information out of mis-speculated execution, leading to at worst arbitrary virtual memory read vulnerabilities across local security boundaries in various contexts. Variants of this issue are known to affect many mode...
