Intel says CPU kernel bug fixes will have negligible impact on average users

(Reuters/Robert Galbraith)Intel is slated to release patches to address the bug.

After an Intel processor bug affecting CPU kernel vulnerability was discovered, the tech giant finally spoke to allay fears of its users.

According to a report from PCWorld, Intel executives confirmed during a conference call on Wednesday that they will roll out patches over the next few weeks to fix the flaw which is now called "side channel analysis exploit." The patches, however, will have some performance effects, noting that they will be at frustrating levels pegged at zero to 30 percent level.

The executives clarified, however, that the performance impact will be negligible when it comes to average PC users. These are the people who use the PC at home. Moreover, Intel also said that it has already informed AMD, ARM, and other operating system vendors of the current vulnerability issue.

Furthermore, the company also said that it will use its own microcode updates to address all of the concerns. Side channel analysis exploit gives cyber attackers the ability to observe the content of privileged memory, which exploits a speculative execution to go around different privilege levels, Intel explained. Through the exploit, attackers may gain access to data, though they do not have the power to modify or delete them, Intel added.

Meanwhile, Microsoft issued an emergency update for Windows to add protection against the processor bug. Sources close to the matter told The Verge that the update will be applied automatically on Windows 10. Moreover, the update will also cover older Windows versions as well as the supported ones. Windows 7 and Windows 8, on the other hand, will not receive the automatic update; instead, they will be updated next Tuesday, the report added.

"We're aware of this industry-wide issue and have been working closely with chip manufacturers to develop and test mitigations to protect our customers," said Microsoft in a statement. "We are in the process of deploying mitigations to cloud services and have also released security updates to protect Windows customers against vulnerabilities affecting supported hardware chips from Intel, ARM, and AMD," it went on to say.
