Description Wade Mealing 2018-11-06 01:21:12 UTC
A flaw was found in computer hardware of the Intel microprocessors related to the instruction-side TLB (Translation Lookaside Buffer) that caches translations from guest (and host) virtual addresses into physical addresses.  

This is a software fix that attempts to prevent exploitation of the hardware through preventing a hacker from creating an exploitable condition
