Beta: CloudLinux 6 kernel updated

CloudLinux 6 kernel version 2.6.32-896.30.1.lve1.4.56 is now available for download from our updates-testing repository.

Changelog:

  • Rebased to OVZ kernel version 2.6.32-042stab130.1

An industry-wide issue was found in the way many modern microprocessors designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently, cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks (CVE-2018-3639).

To install new kernel please run the following command:

yum clean all --enablerepo=cloudlinux-updates-testing && yum install kernel-2.6.32-896.30.1.lve1.4.56.el6 --enablerepo=cloudlinux-updates-testing

Also for modules compatibility, please run kmod packages update:

yum update kmod-*  --enablerepo=cloudlinux-updates-testing
