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 Data Sampling Uncacheable Memory (MDSUM)
Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access...
May 2019 Patch Tuesday – 79 Vulns, 22 Critical, RDP RCE, MDS Attacks, Adobe Vulns
This month's Microsoft Patch Tuesday addresses 79 vulnerabilities with 22 of them labeled as Critical. Of the 22 Critical vulns, 18 are for scripting engines and browsers. The remaining 4 are remote code execution RCE in Remote Desktop, DHCP Server, GDI+, and Word. Microsoft also released guidanc...

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...

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...
