Spectre specter, Meltdown's impact on the processor industry is unprecedented, Intel, AMD, ARM and other processor vendors, Windows, Linux and other operating systems have been impacted, but the degree is different.
Intel has completed repair work on the ghost bug variant of the processor products for the past five years. For the ghost bug variant 2 and the fuse hole, Intel processors will be redesigned in the future to achieve immunity at the hardware level. A generation of Xeon Cascade Lake and the eighth generation of the Core 2D series (suspected 10nm Cannon Lake) in the second half.
So, what happened to AMD here? AMD officials announced the latest progress today.
Compared to Intel’s collective fall, AMD processors were slightly more vulnerable to this vulnerability. Among them, the fusion vulnerability was completely immune due to different architecture designs. The ghost bug variant had been previously repaired through system and software updates, and AMD deliberately emphasized performance impact. Minimal.
For variant 2 of Ghost Vulnerability, AMD previously stated that the risk is almost zero, and there is no evidence that this can be achieved.
AMD pointed out in its latest bulletin that, for variant 2 of Ghost Vulnerability, AMD processor users need not only upgrade microcode updates (ie, flash BIOS) from OEMs and motherboard manufacturers, but also upgrade Windows and Linux to the latest version.
AMD Phantom variant 2 bug patch for Linux system has been released previously. The patch for the latest Windows 10 Version 1709 (Autumn Ideas Update) has also been fully pushed today. Please go to Windows Update and click Update.
In addition, the Windows Server 2016 patch is undergoing final testing and will soon be released.
BIOS microcode updates have also been issued to customers and eco-partners. AMD users only need to upgrade the latest BIOS, and they have been supporting the core products of the first-generation bulldozer architecture.
AMD stated that any subsequent progress will be promptly reported.
It is worth mentioning that AMD had previously stated that 7nm technology, new Zen 2 architecture (expected next year) will be a ghost hole in the hardware level, while the immediate launch of the Ryzen 2000 series despite the 12nm upgrade process and Zen + upgrade framework, but The bottom layer does not change, I believe there will still be loopholes, but the BIOS and system patches will certainly be done in a timely manner.
