New Intel CPU Vulnerability: Lazy FP State Restore
#1
https://www.techpowerup.com/245121/intel...nerability
Quote:The "lazy FP state restore" feature is a set of commands used to temporarily store or restore the FPU states of applications running "lazily" (as opposed to "eagerly"). Red Hat put out an advisory stating that numbers held in FPU registers could be used to access sensitive information about the activities of other applications, including encryption keys. Intel began working with popular OS vendors to quickly roll out software patches against the vulnerability.
