While patches are being worked on -- and in the case of Windows Insiders, have already rolled out -- users of both operating systems can expect to experience something of a performance hit.
For Linux, work is underway in the open source community to patch the problem which affects the kernel's virtual memory system.
Whenever a running program needs to do anything useful – such as write to a file or open a network connection – it has to temporarily hand control of the processor to the kernel to carry out the job.
There is presently an embargoed security bug impacting apparently all contemporary CPU architectures that implement virtual memory, requiring hardware changes to fully resolve.
