title: Meltdown/Spectre vulnerability status for Chrome OS devices
---

This page details status for Chrome OS devices regarding the [Meltdown and
Spectre vulnerabilities](https://meltdownattack.com/), also known as
["speculative execution vulnerabilities" described by Google Project
Zero](https://googleprojectzero.blogspot.com/2018/01/reading-privileged-memory-with-side.html).

## Meltdown

Google has been working on updates that contain the Kernel Page Table Isolation
(KPTI) mitigation for Meltdown. ARM Chrome OS devices are not affected by
Meltdown. Most Intel devices received KPTI with M63. All Intel devices have
received KPTI with M66, and therefore all Intel Chrome OS devices are now
protected against Meltdown.

(2018-May-22: Updated to note that all Intel devices are now protected against
Meltdown.)

### Variant 3 ([CVE-2017-5754](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5754))

hardware for Variant 3
([CVE-2017-5754](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5754)),
which is also referred to as Meltdown.

#### Protection against Variant 3

## Spectre

The following subsections indicate Chrome OS status with respect to the Spectre
vulnerability (also referred to as "Variant 1" and "Variant 2" in the Project
Zero blog post). Spectre potentially allows access to data held in other
processor execution contexts. The victim execution context (kernel or process)
must have certain code patterns in their address space.

### Variant 1 ([CVE-2017-5753](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5753))

The Linux kernel has a feature called eBPF that is used to run untrusted code.
The Project Zero blog post describes how this can be abused by attackers to
generate vulnerable code patterns in the kernel. However, Chrome OS disables
eBPF in its kernels and therefore is not exposed to Spectre Variant 1 via eBPF.
Additional Spectre variant 1 mitigations available in the Chrome browser are
described [here](/Home/chromium-security/ssca).

### Variant 2 ([CVE-2017-5715](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2017-5715))

The Project Zero blog post describes how virtualization can be used to exploit
Spectre Variant 2. Chrome OS devices that ship [Linux
VMs](https://chromium.googlesource.com/chromiumos/docs/+/HEAD/containers_and_vms.md)
contain mitigations for Spectre variant 2.

(2018-Oct-05: Updated to reflect usage of virtualization features on Chrome OS;
fixes for ARM devices on kernel 3.18.)

#### **Intel devices**

On Intel devices we’ve deployed the
[Retpoline](https://support.google.com/faqs/answer/7625886) compiler-based
mitigation for all Chrome OS kernels, starting with Chrome OS 65. This
mitigation prevents kernel-to-user, guest-to-guest, and host-to-guest
information leaks using Spectre variant 2.

#### **ARM devices**

On ARM devices we’ve started integrating firmware and kernel patches [supplied
by ARM](https://developer.arm.com/support/security-update). ARM devices will
receive updated firmware and kernels before they enable virtualization features.

Some ARM devices on 4.4 kernels received Spectre variant 2 fixes with Chrome OS
67. These fixes were later discovered to be incomplete and updated with Chrome
OS 70:

Chrome OS 71:

## Speculative store buffer bypass (variant 4)

### Vulnerability description

Following on their Meltdown and Spectre research, Google's Project Zero
disclosed a fourth variant of their speculative execution attacks, Speculative
store buffer bypass
([CVE-2018-3639](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-3639)).
On Chrome OS this variant affects the Chrome browser and is also mitigated by
[Site Isolation](http://www.chromium.org/Home/chromium-security/site-isolation).

### Chrome OS response

Chrome OS 67 enables Site Isolation by default across the Chrome OS fleet.
Chrome OS 67 will be released on the stable channel around June 5, 2018. Site
isolation may increase memory use by approximately 10%. For more information on
Site isolation, including how to enable it manually, see the [Chrome Help
article](https://support.google.com/chrome/answer/7623121).

### Affected devices

Intel devices with Core processors, or Apollo Lake Atom processors, are affected
by this variant. ARM devices with MTK8173 processors, or RK3399 processors, are
affected by this variant. The cpu line in the chrome:system page will show what
CPU the device has.

67:
