RHSA-2019:2863: Important: kernel security update
First published: Mon Sep 23 2019(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux operating system.<br>Security Fix(es):<br><li> A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. 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)</li>
