The company has decided not to extend these updates to its Ryzen 1000, 2000, and 3000 series processors or its Threadripper 1000 and 2000 models.
Safe to assume that these patches will be provided via operating system updates? Patch to the kernel for Linux users? I see bajillion articles when I look up sinkclose, but nothing about the patch method.
Patch method is BIOS via OEMs. https://www.amd.com/en/resources/product-security/bulletin/amd-sb-7014.html
