ETH Zurich researchers discover new security vulnerability in Intel processors

Computer scientists at ETH Zurich discover new class of vulnerabilities in Intel processors, allowing them to break down barriers between different users of a processor using carefully crafted instruction sequences. Entire processor memory can be read by employing quick, repeated attacks.
  • The new class of vulnerabilities in Intel processors arises from speculative technologies that anticipate individual computing steps.
  • Openings enable gradual reading of entire privilege memory contents of shared processor (CPU).
  • All Intel processors from the last 6 years are affected, from PCs to servers in data centres.

    The so-called BPRC (Branch Predictor Race Conditions) emerge during a brief period of a few nanoseconds when the processor switches between prediction calculations for two users with different permissions, explains Sandro Rüegge, who has been examining the vulnerability in detail over the past few months.
