All computers with Intel chips from the past 10 years appear to be affected, the report said, and patches to Microsoft’s Windows and Apple’s OS X operating systems will be required.

A report that Intel chips are vulnerable to hackers raised concerns about the company’s main products and brand.
On Tuesday, technology website the Register said a bug lets some software gain access to parts of a computer’s memory that are set aside to protect things like passwords. All computers with Intel chips from the past 10 years appear to be affected, the report said, and patches to Microsoft’s Windows and Apple’s OS X operating systems will be required. The security updates may slow down older machinery by as much as 30 percent, according to the Register.
Flaws in the designs of microprocessors, which go through rigorous testing and verification, are usually easily fixed by patches in the code that they use to communicate with the rest of the computer. But if the error can’t be fixed easily in software, it could be necessary to redesign the chip, which can be extremely costly and time consuming.
Intel is expected to put out a statement but hasn’t yet commented on the issue. Historically, the way companies respond to such issues and how quickly they address them has determined how big the problem becomes.
“This is a potential PR nightmare,” said Dan Ives, head of tech research at GBH Insights. “They need to get ahead of this and try to contain any of the damage to customers as well to the brand.”
The report hit Intel shares, which fell as much as 3.8 percent, the most since April, and gave a boost to rival Advanced Micro Devices, which surged as much as 7.3 percent to $11.78 Wednesday. An Intel spokesman declined to comment.
Chip design flaws are exceedingly rare. More than 20 years ago, a college professor discovered a problem with how early versions of Intel’s Pentium chip calculated numbers. Rival International Business Machines was able to make use of the finding and claim Intel products would cause frequent problems for consumers’ computers. While that didn’t happen, Intel had to recall some chips and took a charge of more than $400 million.
Intel’s microprocessors are the fundamental building block of the internet, corporate networks and PCs. The company has added to its designs over the years trying to make computers less vulnerable to attack, arguing that hardware security is typically tougher to crack than software.
The Santa Clara-based company’s chips have more than 80 percent market share overall and more than 90 percent in laptops and servers.
Programmers have been working for two months to try to patch the flaw in open-source Linux system, The Register said, adding that Microsoft was expected to release a patch for the issue soon.
