Oracle Linux is an enterprise-class Linux distribution supported by Oracle and built from source packages for Red Hat Enterprise Linux (RHEL). Some of the special features of Oracle Linux include a custom-build and rigorously-tested Linux kernel called “Oracle Unbreakable Kernel”, tight integration with Oracle’s hardware and software products including most database applications, and “zero downtime patching” – a feature that enables administrators to update the kernel without a reboot. via_distrowatch

Oracle Linux 7.5 is released. The updated version of the revised version mainly relates to the improvement of security and the improvement of support for cloud and container environments.

Unbreakable Enterprise Kernel (UEK) Release 4 (kernel-uek-4.1.12-112.16.4.el7uek) for x86-64
Red Hat Compatible Kernel (kernel-3.10.0-862.el7) for x86-64
Support for Memory Protection Keys on recent Intel processors. This update includes support for the Memory Protection Keys hardware feature on recent Intel processors. CPUs provide this support through a new user-accessible register (PKRU) that contains two separate bits (Access Disable and Write Disable) for each key.
Ability to unlock encrypted devices connected to a network during the boot process. Previously, block devices that were connected to a network could not be unlocked during the boot process because it was not possible to connect and decrypt these devices prior to starting any network services.
SSLv3 disabled in mod_ssl. To improve security for SSL/TLS connections, support for SSLv3 in the default configuration for the httpd mod_ssl module has been disabled. This change also restricts the use of certain cryptographic cipher suites.
KASLR for KVM guests added. Capability for Kernel address-space layout randomization (KASLR) for KVM guests has been added.
