Transient Execution Attacks That Leaks Arbitrary Kernel Memory (ETH Zurich)


A technical paper titled “Inception: Exposing New Attack Surfaces with Training in Transient Execution” was published by researchers at ETH Zurich. Abstract: "To protect against transient control-flow hijacks, software relies on a secure state of microarchitectural buffers that are involved in branching decisions. To achieve this secure state, hardware and software mitigations restrict or... » read more

Prefetch Side Channels Undermine the Isolation Between User and Kernel Space on AMD CPUs


This new technical paper titled "AMD Prefetch Attacks through Power and Time" is from researchers at Graz University of Technology and CISPA Helmholtz Center for Information Security. Note, this is a prepublication paper for the USENIX Security Symposium in Boston in August 2022.   This paper includes countermeasures and mitigation strategies, and the paper indicates that the findings were di... » read more
