Recently, the embargo has been broken on an Intel microprocessor issue that affects operating systems that lazily save floating point unit (FPU) register state: CVE-2018-3665.
While SmartOS is affected by this issue, Intel included Joyent in the embargoed information, with adequate time for us to develop and validate a fix.
Actions Taken by Joyent
The fix has been made available for upstream inclusion and is in the process of being deployed to the Triton Cloud (public cloud). Deployment necessitates a compute node reboot; we are making best effort to schedule those reboots with customers to minimize disruption.
We will also make available SmartOS updates for our software customers.
Further updates will continue to be posted in this advisory.
