Intel CPUs Vulnerable to New 'SGAxe' and 'CrossTalk' Side-Channel Attacks

Cybersecurity researchers have discovered two distinct attacks that could be exploited against modern Intel processors to leak sensitive information from the CPU's trusted execution environments TEE. Called SGAxe, the first of the flaws is an evolution of the previously uncovered CacheOut attack...

hw: L1D Cache Eviction Sampling

A microarchitectural timing flaw was found on some Intel processors. A corner case exists where data in-flight during the eviction process can end up in the “fill buffers” and not properly cleared by the MDS mitigations. The fill buffer contents which were expected to be blank can be inferred usi...
