Google discovers 'serious' flaws in Intel and other chips

"The full Project Zero report is forthcoming", it said.
Vendors have been working feverishly to put out patches throughout the past two days. The other, Spectre, is harder to fix, but also harder to exploit, making it less of an immediate threat to consumer devices.
Both Spectre and Meltdown have the ability to be one of the biggest tech security vulnerabilities discovered.
What are "Spectre" and "Meltdown"?
Intel also says the exploits are due to "speculative execution techniques" which are present in nearly all modern processors.
However, Apple has not published any information on the security fixes for its computers and smartphones to date.
Variant 1 (CVE-2017-5753), "bounds check bypass".
Has anyone been hacked this way yet? In November, researcher Kevin Finisterre discovered a vulnerability in the products of drone manufacturer DJI and reported the issue to the firm.
It breaks down the most fundamental isolation between user applications and the operating system.
Variant 3 (CVE-2017-5754), "rogue data cache load".
In order to do their work, they must move data around, using different types of memory to temporarily store it. Some customers may worry that they have not been protected since they were not asked to reboot their instance. The company in its presentation also says the exploits do not impact just "one architecture or processor implementation".
There has been a significant concern in particular about "Spectre". A virtualisation component known as a hypervisor connects the physical machine to virtual machines. What is it protecting against?
Alex Ionescu, vice president of EDR Strategy at CrowdStrike, applauded all of the work by vendors to mitigate the risks of Meltdown and Spectre. It does so by strictly separating kernel memory spaces in the processor cache. These services, offered by Amazon, Microsoft, Google, IBM and others, give smaller companies access to data centers, web hosting and other services they need to run their businesses.
Although billions of computers and devices are vulnerable, security fixes are already being rolled out.
FLINT DUXFIELD: The Meltdown vulnerability is only a problem for Intel processors, which would be reassuring, were it not for the fact that Intel controls 80 per cent of the PC processing market, and the vulnerability affects computers that date back to 1995.
In the list of results that's displayed, you're looking to see that a series of protections are enabled - this will be listed as True. Google's cloud infrastructure doesn't rely on any single technology to make it secure.
Intel's CEO sold shares in his company several months after Google informed the chipmaker of a serious security problem affecting its products.
After patching its Linux computers on all its computers, Google observed "negligible impact on performance".
While many computer vulnerabilities occur through software, these two flaws exist in the hardware themselves.
