Intel has officially pushed out microcode updates with Spectre and Meltdown mitigations for all of the processors it launched in the past five years. In addition to this, the company’s CEO announced new, redesigned processor lines that will start shipping later this year and will include hardware-based protection for Meltdown (exploiting CVE-2017-5754, a rogue cata cache load flaw) and variant 2 of Spectre (exploiting CVE-2017-5715, a branch target injection vulnerability).
“While [Spectre] Variant 1 will continue to be addressed via software mitigations, we are making changes to our hardware design to further address the other two,” Intel CEO Brian Krzanich announced. “We have redesigned parts of the processor to introduce new levels of protection through partitioning that will protect against both Variants 2 [Spectre] and 3 [Meltdown]. Think of this partitioning as additional ‘protective walls’ between applications and user privilege levels to create an obstacle for bad actors.”
