AMD Will Release CPU Microcode Updates for Spectre Flaw This Week

AMD Will Release CPU Microcode Updates for Spectre Flaw This Week AMD Will Release CPU Microcode Updates for Spectre Flaw This Week

Google says Spectre and Meltdown "represent a new class of attack" and that "they're just a few among the many different types of threats our infrastructure is created to defend against every day".

- Nvidia Corp is updating the software for its graphics processors in response to the Spectre security threat, but its chief executive said on Wednesday its chips were not subject to the same risks as those from Intel and other companies.

Now, however, Google is saying that not only did it know about the three specific Spectre and Meltdown CPU exploits, it worked to patch its own product line against a variant of Spectre that "was going to be much harder to mitigate".

Confusion around the Spectre and Meltdown flaws have been rampant as numerous major tech companies rush to patch their products. In addition, AMD published a security statement that reiterated that position, specifically for the branch target injection flaw. Updates are available for some GeForce, Quadro, Tesla and GRID drivers for both Windows and Linux operating systems.

Two CPU-level vulnerabilities Spectre and Meltdown have affected all chips made in the last two decades by Intel, AMD and AMR. Because the root of the security issues stem from a crucial part of how modern computers run, it will likely take a long time to know how it will affect the tech world in the long-run.

Businesses which use servers and cloud data with NVIDIA GPUs also seem to have nothing to fear since NVIDIA's latest update for its GeForce drivers aims to prohibit any unauthorized access to the GPU. He also promises that the remainder of those products will have patches out by the end of January, and then says the company will continue to issue fixes for older products "as prioritized by [its] customers". "We are patching the CPU vulnerability the same way that Amazon, the same way that SAP, the same way that Microsoft, etc is patching because we have software as well", said Huang.

The first approach Google's engineers took was to switch off CPU features that rendered chips vulnerable to intrusion.
