They're not affected by these security issues, ' Huang told attendees at a press briefing during the Consumer Electronics Show (CES) late last night. Also they point out that the software updates to protect PCs will have performance impacts.

Meltdown and Spectre are two recently-revealed system-level bugs that affect the processors in virtually every PC and smartphone now in circulation. As reported by Bleeping Computer, however, after the launch of the problematic patch, two new updates - USN-3522-3 and USN-3522-4 - which include the problem-free Linux kernel image 4.4.0-109 have been released by Canonical.

It said it had no reason to believe the drivers were troubled by the second flaw, dubbed Meltdown.

While the full extent of devices affected by the flaws is not yet fully known, Cisco Systems has said it has identified 18 vulnerable products and is looking for problems in almost 30 other products, including switches and routers.

The Ubuntu issue is the first case of users on Linux distributions experiencing problems with fixes for the Meltdown and Spectre bugs.

Nvidia's shares ended the day up 0.78% higher at $223.68.

Affected companies, keen to quash any speculation that the flaws could require the replacement of millions of chips or provoke lawsuits caused by slowing computer performance, have been striving to play down the scale of the threat. "We are patching the CPU vulnerability the same way that Amazon, the same way that SAP, the same way that Microsoft, etc are patching, because we have software as well". "Anybody who has software needs to patch", Huang said.

Huang added: "I am absolutely certain that our GPU is not affected". "But their processors like the Tegra and the Tesla, the ARM-based processors that they sell are going to be exposed to the Spectre exploits, just like everybody else".

Intel, Microsoft and Linux developers have all endeavoured to rush out fixes to mitigate risks from the flaws - with the worst, labelled Meltdown, affecting only Intel CPUs.

The release comes amid a debate about the performance impact of the software fixes for Spectre and Meltdown.
