Intel warns patches for chip flaws are buggy

Intel warns patches for chip flaws are buggy

He added, "If this requires a revised firmware update from Intel, we will distribute that update through the normal channels".

The flaws affect billions of systems globally across AMD, ARM and Intel designs. For instance, cryptographer Paul Kocher told Scientific American this week that Meltdown and Spectre demonstrate a "failure of thought and attention" by chipmakers looking to balance security and performance needs.

"We have received reports from a few customers of higher system reboots after applying firmware updates", Intel EVP Navin Shenoy said in a statement.

"Specifically, these systems are running Intel Broadwell and Haswell CPUs for both client and data centre".

In the fallout of the discovery of Spectre and Meltdown, companies have been racing to patch vulnerabilities.

Intel have released an analysis of post-mitigation performance impact, along with a table of benchmarks testing various CPUs from their last three processor generations. The Wall Street Journal is reporting it got its hands on a confidential memo issued by the company and shared with large companies and cloud providers not to install the patches. Even if it turns out to be as good as Google's folks say it is, it's still a solution that is a ways off, because vendors need time to incorporate Google's suggestions, validate them, and then turn them into updates. Patches should be available for most of its chips made in the past five years, CEO Brian Krzanich said at the CES trade show in Las Vegas this week.

Since the second version of Spectre needs a different fix, AMD will also provide its customers and partners for Ryzen and EPYC processors with a patch for its chips starting this week.

Recent reports have revealed that in the wake of the panic caused by the reveal of chipset flaws called Meltdown and Spectre, Nvidia has released a software patch for their CPUs. The idea that cloud giants are experiencing less pain from Spectre and Meltdown could also give weight to the argument that public cloud security could, in fact, be stronger than most in-house efforts. We believe our GPU hardware is immune to the reported security issue.

The security patches by Nvidia relate to software drivers that let its chips work with operating systems like Windows.
