Putting it all together, I would not be surprised if we start 2018 with the release of the mother of all hypervisor privilege escalation bugs, or something similarly systematic as to drive so much urgency, and the presence of so many interesting names on the patch set’s CC list.technology bullshit security container

there is presently an embargoed security bug impacting apparently all contemporary CPU architectures that implement virtual memory, requiring hardware changes to fully resolve. Urgent development of a software mitigation is being done in the open and recently landed in the Linux kernel, and a similar mitigation began appearing in NT kernels in November. In the worst case the software fix causes huge slowdowns in typical workloads. There are hints the attack impacts common virtualization environments including Amazon EC2 and Google Compute Engine, and additional hints the exact attack may involve a new variant of Rowhammer.linux kernel security
