MELTWEB: A Transient Execution Attack to Capture Data in Fill Line Buffer.

The out-of-order execution mechanism is widely used in modern processors. However, meltdown attacks exploit this mechanism to allow malicious instructions to capture sensitive data from kernel domains. This work aims to present a new meltdown attack, called Meltweb. It is a new approach in the category of privileged speculative execution attacks to leak arbitrary data into address spaces and privi...
