Hardware security bug
In digital computing, hardware security bugs are a class of vulnerabilities affecting computer central processing units (CPUs) which allow data to be read by a rogue process when such reading is not authorized. Such vulnerabilities are considered "catastrophic" by security analysts.[1][2][3] These vulnerabilities are based on exploiting side effects of speculative execution, a technique used by many high performance CPUs to improve processing speed.
