In Summary :
We have discovered a new application of speculative execution attacks, bypassing hardware-based memory protections. Vulnerabilities affecting speculative execution of modern processor architectures were first discovered in 2017 by Jann Horn of Google Project Zero and other security researchers. This class of vulnerabilities allows local unprivileged attackers to expose the contents of protected memory by exploiting the microarchitectural capabilities of modern out-of-order CPUs such as caching, instruction pipeline or speculative execution.
