Microarchitectural vulnerabilities, such as Meltdown and Spectre, exploit subtle
microarchitecture state to steal the user's secret data and even compromise the operating …

Transient execution attacks, also known as speculative execution attacks, have drawn much
interest in the last few years as they can cause critical data leakage. Since the first …

This paper studies the synergies between memory corruption vulnerabilities and speculative
execution vulnerabilities. We leverage speculative execution attacks to bypass an important …

Spectre, Meltdown, and related attacks have demonstrated that kernels, hypervisors, trusted
execution environments, and browsers are prone to information disclosure through micro …

Speculative execution attacks present an enormous security threat, capable of reading
arbitrary program data under malicious speculation, and later exfiltrating that data over …

Speculative execution attacks like Meltdown and Spectre work by accessing secret data in
wrong-path execution. Secrets are then transmitted and recovered by the attacker via a …

Speculation-based attacks affect hundreds of millions of computers. These attacks typically
exploit caches to leak information, using speculative instructions to cause changes to the …

Speculative execution, the base on which modern high-performance general-purpose CPUs
are built on, has recently been shown to enable a slew of security attacks. All these attacks …

This paper describes context-sensitive fencing (CSF), a microcode-level defense against
multiple variants of Spectre. CSF leverages the ability to dynamically alter the decoding of …

Recent security vulnerabilities that target speculative execution (eg, Spectre) present a
significant challenge for processor design. These highly publicized vulnerabilities use …
