Spectre without shared memory
Ben Amos, Niv Gilboa, Arbel Levy · 2019
The Spectre attack by Kocher et al. [11] reads arbitrary data from colocated processes by exploiting two common features of modern processors: speculative execution and shared caches. While theoretically the attack works in many different settings, the current variations all require that the attacker share with the target a memory region that includes vulnerable code which accepts input from the attacker.
