Boffins based in Germany and Austria have found a flaw in AMD’s SEV trusted execution environment that makes it less than trustworthy. The researchers – Ruiyi Zhang, Lukas Gerlach, Daniel Weber, Lorenz Hetterich, and Michael Schwarz (all with CISPA Helmholtz Center for Information Security), Youheng Lü (independent), Andreas Kogler (Graz University of Technology) – call the vulnerability CacheWarp for its ability to create inconsistencies between cache lines and memory.
