Detecting speculative leaks with compositional semantics
Xaver Fabian, Marco Guarnieri, Boris Köpf +4
Speculative execution enhances processor performance by predicting intermediate results and executing instructions based on these predictions. However, incorrect predictions can le…
Enter, Exit, Page Fault, Leak: Testing Isolation Boundaries for Microarchitectural Leaks
Oleksii Oleksenko, Flavien Solt, Cédric Fournet +3
CPUs provide isolation mechanisms like virtualization and privilege levels to protect software. Yet these focus on architectural isolation while typically overlooking microarchitec…
Hardware-Software Contracts for Secure Speculation
Marco Guarnieri, Boris Köpf, Jan Reineke +1
Since the discovery of Spectre, a large number of hardware mechanisms for secure speculation has been proposed. Intuitively, more defensive mechanisms are less efficient but can se…
Flushgeist: Cache Leaks from Beyond the Flush
Pepe Vila, Andreas Abel, Marco Guarnieri +2
Flushing the cache, using instructions like clflush and wbinvd, is commonly proposed as a countermeasure against access-based cache attacks. In this report, we show that several In…
