Google released a new version of its Linux-based Chrome OS operating system for Chromebooks, which offers additional Meltdown and Spectre mitigations.
Chrome OS 65.0.3325.167 (Platform version: 10323.58.0/1), is going out to supported Chromebooks.
The new version has fixes for bugs along with other security updates, including KPTI (Kernel page-table isolation) mitigation against the Meltdown vulnerability for Intel-powered Chromebooks running on Linux kernel 3.14.
In addition, Chrome OS 64 brings the Retpoline mitigation against the second variant of the Spectre security vulnerability to all Chromebooks powered by Intel processors. The new Meltdown and Spectre patches are here to complement the previous ones Google released last month.
Among the enhancements in the new Chrome OS release, there is a way a user can view local files from search results in the Launcher and automatic re-enrollment of managed devices, support for device-wide certificates in Security Assertion Markup Language (SAML) Single Sign-On (SSO) sign-in.
Chrome OS 65 also adds support for the MIDI API to Chromebooks capable of running Android apps, the ability for users to display a short video recording on their profile pictures, Select-to-Speak word highlighting functionality with extra options, as well as a new tablet setup screen with advanced options.
