2. Relevant releases/architectures:

Red Hat Enterprise Linux Server AUS (v. 6.6) - noarch, x86_64
Red Hat Enterprise Linux Server Optional AUS (v. 6.6) - x86_64
Red Hat Enterprise Linux Server Optional TUS (v. 6.6) - x86_64
Red Hat Enterprise Linux Server TUS (v. 6.6) - noarch, x86_64

3. Description:

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)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
