CentOS Errata and Security Advisory CESA-2019:2863

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

Security Fix(es):

  • 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)

Merged security bulletin from advisories:
https://lists.centos.org/pipermail/centos-announce/2019-September/085618.html

Affected packages:
kernel
kernel-abi-whitelists
kernel-debug
kernel-debug-devel
kernel-devel
kernel-doc
kernel-firmware
kernel-headers
perf
python-perf
