Kernel 4.9.161 doesn't have the patch for CVE-2019-8912 yet so we might wait until it get released. I updated my PR: https://github.com/CentOS-virt7/xen-kernel/pull/18 https://repo.aerisnetwork.com/archive/kernel-4.9.161-34.el6.x86_64.rpm https://repo.aerisnetwork.com/archive/kernel-4.9.161-34.el7.x86_64.rpm Anthony Perard already tried to build my PR on the CBS but he was not able to enable the SCL repo ( http://mirror.centos.org/centos/$releasever/sclo/$basearch/rh/) to get devtoolset-7. We might need to get help from centos-devel.
