Reuters – Nvidia 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.
“Our GPUs are immune,” Nvidia chief executive Jensen Huang said during an event at the Consumer Electronics Show in Las Vegas, referring to graphics processing units, the chip maker’s key product.
“They are not affected by these security issues.”
Huang’s comments illustrate how technology sellers from cloud-based datacentre providers to anti-virus companies are scrambling to guard against flaws disclosed last week in chips made by Intel and others.
Security researchers revealed vulnerabilities, dubbed Meltdown and Spectre, that could let hackers steal passwords or encryption keys from central processing units (CPUs) made by Intel and rivals. CPUs are used on personal computers, smartphones, servers and other devices.
The security patches unveiled by Nvidia relate to software drivers that let its chips work with operating systems like Windows. While Nvidia said its GPUs are not flawed, it was updating its drivers because they interact with potentially vulnerable CPUs.
It said it had no reason to believe the drivers were troubled by the second flaw, dubbed Meltdown.
Intel published data that showed the recent security updates did not have a significant performance impact.
The data included three generations of processor platforms running Microsoft's Windows 10 and Windows 7 operating systems, Intel vice president Navin Shenoy said.
