Academic researchers from multiple universities recently discovered a new Spectre-like method of extracting secrets from modern Intel processors. However, Intel says that the original Spectre mitigation fixes these flaws, too.
A group of researchers from the University of California San Diego, Purdue University, UNC Chapel Hill, Georgia Institute of Technology, and Google, discovered that a feature in the branch predictor called the Path History Register (PHR) can be tricked to expose sensitive data.
