A speculative execution vulnerability has been discovered in AMD Zen 2 CPUs.
This vulnerability has been dubbed “Zenbleed”.

A malicious actor could steal sensitive data, such as passwords and encryption keys,
resident in the CPU cores. Sensitive data could be extracted from any system operations,
including those that take place in virtual machines, isolated sandbox environments,
and containers. Even a malicious webpage, running some carefully crafted JavaScript,
could exploit Zenbleed to snoop on information. Read more in our SVG advisory.
