The Intel processors found a serious vulnerability. Again
Not so long ago there was a story with a critical vulnerability of Intel processors, during which the company even refused to release a patch for some of its processors. But some time ago, the processors of the world famous companies were again in the spotlight. This time, experts from Google and Microsoft have found an error, the correction of which may lead to a significant slowdown of the devices.
According to Intel's press service, in November last year as part of a coordinated vulnerability disclosure program (Coordinated Vulnerability Disclosure), Microsoft informed the manufacturer of processors of the new vulnerability. A little later, a similar statement was received and from Google. The new "hole" in the safety of the structure is similar to Spectre and Meltdown, are giving hackers access to the core processor memory, allowed to get their hands on passwords and other confidential information. A new vulnerability called Speculative Store Bypass (variant 4), and the Chrome browser, and Safari Edge An already released a patch that partially solve this problem. In this case, after updating the browser from Microsoft, many users began to complain about the shutdown and reboot your PC. For the final remedy the situation will need to update the firmware chips. Software that is already being tested, and its release is scheduled for the "next few weeks". However, the inclusion of protection against new vulnerabilities reduces the performance of processors 2-8%, and in some cases up to 10%. Therefore, many users may be faced with a choice: to jeopardize their personal data or receive less powerful processor.
