New Attacks Against Secure Enclaves

The article describes a newly released low-cost physical attack named TEE.fail that can defeat modern secure enclaves (Confidential Compute, SEV-SNP, TDX/SDX) across major CPU vendors by placing a small hardware device between a memory chip and the motherboard and requiring a compromised OS kernel; it works on DDR5 and significantly weakens the threat model for TEEs.
