Red Hat Security Advisory: Red Hat CloudForms 4.1 security update

This advisory addresses speculative execution vulnerabilities affecting the Linux kernel used in Red Hat CloudForms 4.1 virtual machines. The vulnerabilities, known as Spectre and Meltdown variants (CVE-2017-5753, CVE-2017-5715, CVE-2017-5754), allow unprivileged attackers to read privileged memory via cache side-channel attacks. These issues stem from hardware design flaws in modern microprocessors and cannot be fully fixed by software alone. The update provides software mitigations for x86-64 architectures, which may impact system performance.
