New Windows hack warning: Patch Intel systems now to block SWAPGSAttack exploits

A newly uncovered vulnerability affecting every Windows computer using an Intel processor built since 2012 could allow attackers to bypass safeguards and access information held in a system’s protected kernel memory.

This new side-channel attack is built on previous research into other CPU vulnerabilities – such as Spectre and Meltdown – but this new vulnerability can bypass the protections that were implemented to protect users from attacks exploiting those flaws.

The bug has been called SWAPGSAttack because it exploits SWAPGS, an instruction for x86/x64 CPUs that switches the system to start addressing the protected memory set aside for operating system kernels.
