CVE-2018-12126 [MEDIUM] x86/speculation/mds: Add basic bug infrastructure for MDS
x86/speculation/mds: Add basic bug infrastructure for MDS
Microarchitectural Data Sampling (MDS), is a class of side channel attacks
on internal buffers in Intel CPUs. The variants are:
- Microarchitectural Store Buffer Data Sampling (MSBDS) (CVE-2018-12126)
- Microarchitectural Fill Buffer Data Sampling (MFBDS) (CVE-2018-12130)
- Microarchitectural Load Port Data Sampling (MLPDS) (CVE-2018-12127)
MSBDS leaks Store Buffer Entries which can be speculatively forwarded to a
dependent load (store-to-load forwarding) as an optimization. The forward
can also happen to a faulting or assisting load operation for a different
memory address, which can be exploited under certain conditions. Store
buffers are partitioned between Hyper-Threads so cross thread forwarding is
not possible. But if a thr

A list of impacted products can be found here: https://www.intel.com/content/dam/www/public/us/en/documents/corporate-information/SA00233-microcode-update-guidance_05132019.pdf
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 logic into these

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 guidance on the recently disclosed Microarchitectural Data Sampling (MDS) techniques, known as ZombieLoad, Fallout, and RIDL. Adobe’s Patch Tuesday includes patches for vulnerabilities in Flash, Acrobat/Reader (83 vulnerabilities!) and Media Encoder.
UPDATE May 15: Microsoft has also issued Remote Desktop patches for Windows XP and Server 2003.

CVE-2018-12126 hardware: Microarchitectural Store Buffer Data Sampling (MSBDS)
A flaw was found in many Intel microprocessor designs related to possible information leak of the processor store buffer structure which contains recent stores (writes) to memory..
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 logic into these sub-operations for optimized writes. Both of these sub-operations write to a shared distributed processor structure called the 'processor store buffer'.
The processor store buffer is conceptually a table of address, valu

Data Sampling on MDS-resistant 10th Generation Intel Core (Ice Lake)
## Abstract
Microarchitectural Data Sampling (MDS) is a set of hardware vulnerabilities in Intel CPUs that allows an attacker to leak bytes of data from memory loads and stores across various security boundaries.
On affected CPUs, some of these vulnerabilities were patched via microcode updates.
Additionally, Intel announced that the newest microarchitectures, namely Cascade Lake and Ice Lake, were not affected by MDS.
While Cascade Lake turned out to be vulnerable to the ZombieLoad v2 MDS attack (also known as TAA), Ice Lake was not affected by this attack.
In this technical report, we show a variant of MSBDS (CVE-2018-12126), an MDS attack, also known as Fallout, that works on Ice Lake CPUs.
This variant was automati

## Abstract
Recently, out-of-order execution, an important performance optimization
in modern high-end processors, has been revealed to pose a significant security
threat, allowing information leaks across security domains.
In particular, the Meltdown attack leaks information from the operating system
kernel to user space, completely eroding the security of the system.
To address this and similar attacks, without incurring the performance costs of
software countermeasures, Intel includes hardware-based defenses in its
recent Coffee Lake R processors.
In this work, we show that the recent hardware defenses are not sufficient.
Specifically, we present , a new transient execution attack
that leaks information from a previously unexplored microarchitectural component called
