Red Hat Says Security Updates for Meltdown and Spectre Bugs May Affect Performance

The Meltdown and Spectre vulnerabilities (CVE-2017-5753, CVE-2017-5715, and CVE-2017-5754) were publicly disclosed earlier today as critical hardware flaws affecting modern microprocessors made in the last two decades. These can be exploited by an unprivileged attacker to bypass hardware restrictions through three unique attack paths and gain read access to privileged memory. Red Hat Product Security provided us with several resources to better understand the impact of these hardware bugs on any of their supported Linux-based operating systems from an open source technology perspective. They said that Intel, AMD, POWER 8, POWER 9, IBM System z, and ARM chips are affected by the newly discovered vulnerabilities.
