windows 10 updates fix CPU

Google’s cyber security researchers spotted a major flaw recently in the designing of Intel CPUs and users are not happy at all. This security issue is not that new after all. It looks like it has been around for ten years.

The good news is that a fix is already available to help you get rid of this problem. Microsoft recently pushed a series of updates aimed at patching this particular vulnerability.

The fix reached users before Patch Tuesday

The updates that delivered the fix require a significant redesign of the OS. Unfortunately, this involves reducing the overall performance of the operating system. The complete detailed information about this issue will not be revealed to the public until the flaw that we mentioned above has been fully fixed. According to the latest reports, there are some exciting details regarding the weakness and what is actually broken.

The flaw’s details

It seems that this flaw can allow malicious programs to access some areas of an OS that they usually are not supposed to be accessed, and we are referring to the kernel memory.

The kernel is a high and mighty authority in the architecture of an OS, and it features the highest privileges to read/write instructions and files. If the processor can’t enforce the privileges, this flaw will let other standard programs access the restricted locations such as natively coded programs and content on the web using JavaScript.

Fixing the flaw

To fix this flaw, developers would have to separate the Kernal Memory from the user processor via Kernal Page Table Isolation, and this could result in slowing down the PC. The chance for slowing down the computer is of 5-30% after the update is applied to fix the flaw. The flaw affects only computers with Intel processors and the ones with AMD CPUs are not affected.
