RHEL 7.7 Beta Comes With MDS/Zombieload Mitigations
While Red Hat Enterprise Linux 8.0 has been under GA since early May, RHEL 7.7 is the latest continuation of RHEL7 as part of their ten-year lifecycle. The Red Hat Enterprise Linux 7.7 release will also mark the end of the "full support phase" for the RHEL7 lifecycle.
With the Red Hat Enterprise Linux 7.7 Beta there are mitigations in place for the Microarchitectural Data Sampling (MDS) / Zombieload vulnerabilities affecting Intel CPUs. Also on the CPU vulnerability front, Retpolines are now in place rather than IBRS as the default Spectre Variant Two mitigation to lower the performance overhead and also matches the behavior of RHEL 8.0.
The RHEL 7.7 Beta also includes updates to their network stack, access to Red Hat Insights as part of the RHEL subscription, and other changes. RHEL 7.7 also adds new Python 3 packages that were previously part of the Red Hat Software Collections.
