Massive security flaw found in Intel Processors

There is a huge screw-up in all Intel processor that is produced in the last decade. the processors have a major security hole that could allow normal user programs from database applications to Java Script in web browsers to anticipate some extent layout that is protected by kernel memory areas.
Actually, modern Intel processors have a design flaw that could allow malicious programs to read protected areas of a device’s kernel memory. This flaw could potentially expose protected information like passwords. Because the error is baked into the Intel x86-64 hardware, it needs an OS level overwrite to patch on every major operating system, including Windows, Linux, and macOS.
The exact details of the design flaw and to what extent users are susceptible that are being kept under wraps for now. As for the Register, though since developers appear to be rushing towards patching systems in coming weeks is likely to be very bad.
After all the fix involves severing kernel memory from user processes, patched OSes could potentially see a massive performance hit of five to 30 percent slowdown, depending on the task and processor model.
Five to 30 percent is a jaw-dropping number, but because of all the secrecy right now it’s difficult to tell how noticeable the impact will be for consumer use. For the average user, it is possible that the impact will be negligible. It is also possible that a better implementation of the solution in furtue patches could reduce the performance hit.
One problem with exploits is that even if this one is buried so deep it took ten years to find it, there’s no putting the cat back in the bag post discovery. At least, the tiny portion of the market running AMD processors has some grounds to feel gratified about themselves.
