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...
hardware: Microarchitectural Store Buffer Data Sampling (MSBDS)
Modern Intel microprocessors implement hardware-level micro-optimizations to improve the performance of writing data back to CPU caches. The write operation is split into STA STore Address and STD STore Data sub-operations. These sub-operations allow the processor to hand-off address generation...
hardware: Microarchitectural Fill Buffer Data Sampling (MFBDS)
A flaw was found in the implementation of the "fill buffer", a mechanism used by modern CPUs when a cache-miss is made on L1 CPU cache. If an attacker can generate a load operation that would create a page fault, the execution will continue speculatively with incorrect data from the fill buffer...

Intel CPUs Impacted By New Class of Spectre-Like Attacks
A new class of side channel vulnerabilities impacting all modern Intel chips have been disclosed, which can use speculative execution to potentially leak sensitive data from a system’s CPU. Intel said that the newest class of vulnerabilities, dubbed Microarchitectural Data Sampling MDS, consist o...
