Intel warns Meltdown and Spectre patches could cause slowdowns

Intel warns Meltdown and Spectre patches could cause slowdowns”

The Windows patch is already rolling out to the majority of AMD users, but there was a bug that caused some systems powered by older AMD CPUs to not boot.

In addition to other promises, Intel is committing to publically identify future vulnerabilities and "share hardware innovations that will accelerate industry-level progress in dealing with side-channel attacks". And if you have an AMD Radeon GPU, there's also no need to worry.

While processor manufacturer AMD initially claimed their chips were not vulnerable to Speculative Execution flaws, later research showed that this was not completely true and that flaws in Speculative Execution could allow hackers to exfiltrate data from your PC. Almost every Intel (INTC) computer processor made starting in 1995 is vulnerable to both Meltdown and Spectre - a situation Intel CEO Brian Krzanich said, during a CES 2018 keynote, would be addressed within the next week or so. "I am very proud of how our industry has pulled together and want to thank everyone for their extraordinary collaboration".

Two US lawmakers are calling for an investigation into whether Intel's CEO, Brian Krzanich, improperly sold company stock after learning of a serious security flaw in the tech giant's ' microchips but before it was publicly disclosed. However it is supplying driver updates to "mitigate the CPU security issue".

"By 15 January, we will have issued updates for at least 90 percent of Intel CPUs introduced in the past five years, with updates for the remainder of these CPUs available by the end of January". We are working quickly with these customers to understand, diagnose and address this reboot issue.

However, the Wall Street Journal reports that Intel is quietly advising some customers to hold off installing patches because some of the patches have bugs of their own.

'We have received reports from a few customers of higher system reboots after applying firmware updates, ' explains Intel's Navin Shenoy in a security update. "We are also working directly with data centre customers to discuss the issue".

Last week the stock rose almost 20 percent as investors speculated AMD could wrest market share from Intel, whose chips are exposed to risks from possible Meltdown and Spectre attacks. However, it is believed that this threat will be contained with an operating system patch.

When news of the chip-architecture vulnerabilities was released last week, the chip designer said its devices were only affected by one of the Spectre flaws and claimed that the risk of exploit was "near zero".
