CentOS Errata and Security Advisory CESA-2019:2829

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. (CVE-2019-14835)
