Extended Update Support.
Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es) :
* Modern operating systems implement virtualization of physical memory
to efficiently use available system resources and provide inter-domain
protection through access control and isolation. The L1TF issue was
found in the way the x86 microprocessor designs have implemented
speculative execution of instructions (a commonly used performance
optimisation) in combination with handling of page-faults caused by
terminated virtual to physical address resolving process. As a result,
an unprivileged attacker could use this flaw to read privileged memory
of the kernel or other processes and/or cross guest/host boundaries to
read host memory by conducting targeted cache side-channel attacks.
(CVE-2018-3620, CVE-2018-3646)
* kernel: kvm: vmx: host GDT limit corruption (CVE-2018-10901)
