F**CKWIT, aka KAISER, aka KPTI, Meltdown & Spectre – Intel CPU flaw needs low-level OS patches.
A fundamental design flaw in Intel’s processor chips has forced a significant redesign of the Linux and Windows kernels to resolve the chip-level security bug. Similar operating systems, such as Apple’s 64-bit macOS, will also need to be updated – the flaw is in the Intel hardware and the only was to fix it is at the Operating System level – or worst case to be totally sure you can go buy a new processor without the design fault.
Microsoft have already released an update which will automatically be applied to Windows 10 machines. For users running any other Operating System we recommend you manually check and apply any pending system updates to ensure you are protected. Antivirus providers are also reacting by releasing software updates to combat any potential risks from the newly discovered flaw.
If you run Sophos (our recommended security software) then you are already protected as updates were released on January 5th. You can read more here – https://community.sophos.com/kb/en-us/128053
