[libvirt] [PATCH 0/2] Mitigation for Microarchitectural Data Sampling CPU flaws

[Jiri Denemark]

This series introduces the libvirt side of mitigations for
Microarchitectural Data Sampling microprocessor flaws (CVE-2018-12126,
CVE-2018-12127, CVE-2018-12130, CVE-2019-11091) which were
published earlier today.

To protect your system against possible attacks exploiting these flaws
updates to the CPU microcode, Linux kernel, and virtualization stack
(QEMU, libvirt, and higher management apps) are required.

See https://access.redhat.com/security/vulnerabilities/mds for more
details and additional links.


Both patches have already been pushed.
