Additional Spectre variant 1 mitigations available in the Chrome browser are described here.

However, Chrome OS disables eBPF in its kernels and therefore is not exposed to Spectre Variant 1 via eBPF. The Project Zero blog post describes how this can be abused by attackers to generate vulnerable code patterns in the kernel. Variant 1 ( CVE-2017-5753) The Linux kernel has a feature called eBPF that is used to run untrusted code. The victim execution context (kernel or process) must have certain code patterns in their address space. Spectre potentially allows access to data held in other processor execution contexts. 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).

This is considered a hardware vulnerability and is thus moreĭifficult to mitigate by software means. The reboots concluded at 7:00 AM EST, and with very few exceptions, all are now patched against the exploit.ĬPU exploits known as Meltdown and Spectre that can be used to monitorĪnd intercept private information from a computer's operating This required a reboot of each of the servers in order to move to the new patched kernel. Update: Due to the seriousness of the issue and due to the security implications, we made the decision to apply the updates to all of our servers.
