Linux kernel recently fixed a couple of vulnerabilities that could allow an attacker to bypass mitigations designed to protect devices against Spectre attacks. In January 2018, White hackers from Google Project Zero disclosed vulnerabilities, affecting all modern Intel CPUs, dubbed Meltdown and Spectre.

Both vulnerabilities have been addressed with the release of kernel updates in March, several major Linux distributions, including Debian, Ubuntu and Red Hat, already implemented them.”]
