The '''Microarchitectural Data Sampling''' ('''MDS''') [[vulnerability (computing)|vulnerabilities]] are a set of weaknesses in [[Intel CPUs|Intel x86 microprocessors]] that use [[hyper-threading]], and leak data across protection boundaries that are architecturally supposed to be secure. The attacks exploiting the vulnerabilities have been labeled '''Fallout''', '''RIDL''' (''Rogue In-Flight Data Load'') and, '''ZombieLoad'''.<ref name="new"/><ref>[https://www.heise.de/security/meldung/Spectre-NG-Luecken-OpenBSD-schaltet-Hyper-Threading-ab-4087035.html Spectre-NG-Lücken: OpenBSD schaltet Hyper-Threading ab], heise.de, 2018-06, accessed 2019-09-29</ref><ref>[https://www.youtube.com/watch?v=sDrRvrh16ws&t=75 Let's Talk To Linux Kernel Developer Greg Kroah-Hartman | Open Source Summit, 2019], TFIR, 2019-09-03</ref>, and '''ZombieLoad 2'''.<ref>{{Cite web|url=https://www.forbes.com/sites/daveywinder/2019/11/13/zombie-inside-intel-confirms-zombieload-2-security-threat/|title=Intel Confirms ‘ZombieLoad 2’ Security Threat|last=Winder|first=Davey|date=2019-11-13|website=[[Forbes]]|language=en|url-status=live|archive-url=https://archive.md/4Bpza|archive-date=2020-01-14|access-date=2020-01-14}}</ref>
