Intel processors are vulnerable to a new attack known as SGAxe that breaches the security guarantees of Intel Software Guard eXtensions (SGX) enclaves. It is designed to specifically target and leak data from Intel processors.

SGAxe is an evolution of the CacheOut attack (also known as L1D Eviction Sampling) previously disclosed by researchers at the University of Michigan, University of Adelaide, and Data61 in January 2020.
