"While Intel tests, updates and deploys new microcode, we are making available an out of band update that specifically disables only the mitigation against Spectre variant 2 [which is the buggy patch]".
The Journal has reported that the company notified some of its customers about the security flaws found in its processors, named Spectre and Meltdown.
This means that the issues the Intel patch caused were deemed more serious than the security vulnerabilities it was created to fix - at least in the short term.
"We have received reports from a few customers of higher system reboots after applying firmware updates", an Intel advisory notes.
Microsoft said that its internal testing shows the patch will stop the rebooting until Intel gets a new update together.
Microsoft's update is available for Windows 10, Windows 8.1 and Windows 7, though users will need to download it manually to put it into action.
The Journal said an Intel spokesman refused to identify the companies it told about Spectre and Meltdown before its planned announcement, and the company was unable to tell the US government, or everyone else it meant to, because the news about the flaws got out earlier than Intel expected.
An Intel spokesperson said that the company was unable to notify others, including the United States government, as the bugs were made public earlier than the decided date which was January 9.
A small group of Chinese companies were alerted, however, setting up the "near certainty" China was made aware of security in the cloud before the US, as Williams surmised.
"Security is a top priority for Intel, foundational to our products, and it's critical to the expanse of our data-centric strategy", Krzanich explained to investors, adding that they are, at least for the short term, working on "high-quality mitigations" to protect clients from the security issues found on Intel's chips.
Intel is "working around the clock to ensure we are addressing these issues", Navin Shenoy, executive vice president and general manager of Intel's Data Center Group, said in an update last week. Security is a top priority of Intel.
