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.

All Intel processors since 2018 are affected by Branch Privilege Injection.
In brief

• 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.
