“Preventing data collisions in hardware is a highly complex redesign of general-purpose CPUs, which we think is unlikely to happen in the near future due to the number of shared hardware components in a CPU”
Graz researchers say the leak comes from how every CPU is built, so Intel, AMD and Arm are all in. AMD’s advice for Ryzen owners is to disable core boost, which means paying in performance for a bug AMD calls a lab curiosity. The researchers say it also strengthens PLATYPUS and Hertzbleed. A flaw that sharpens other flaws is not low-risk.
