hardware: Micro-architectural Load Port Data Sampling - Information Leak (MLPDS)

Microprocessors use a ‘load port’ subcomponent to perform load operations from memory or IO. During a load operation, the load port receives data from the memory or IO subsystem and then provides the data to the CPU registers and operations in the CPU’s pipelines. Stale load operations results ar...

hw: cpu: speculative store bypass

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions a commonly used performance optimization. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the...

CVE-2018-3640

CVE-2018-3640 affects macOS EFI/Hypervisor components on macOS High Sierra 10.13.6 and Mojave 10.14, where systems with speculative execution and speculative reads of system registers may leak information via a side‑channel. The root cause is speculative execution side‑channel disclosures; a micr...
