RIDL: Rogue in-flight data load
We present Rogue In-flight Data Load (RIDL), a new class of speculative unprivileged and
constrained attacks to leak arbitrary data across address spaces and privilege boundaries …

Spectre attacks: Exploiting speculative execution
Modern processors use branch prediction and speculative execution to maximize
performance. For example, if the destination of a branch depends on a memory value that is …

Translation leak-aside buffer: Defeating cache side-channel protections with {TLB} attacks
To stop side channel attacks on CPU caches that have allowed attackers to leak secret
information and break basic security mechanisms, the security community has developed a …
