Intel announced this week that it has found another flaw in its Core-based processors called Lazy FP state restore which can theoretically be exploited to pull data from even software on computers running any OS.
Red Hat Computer Architect Jon Masters said that the speculative execution vulnerability allows the floating point registers to be leaked from another process, even the same registers used for crypto. It does not, however, affect AMD processors.
Masters said that the fix, which is currently available on Red Hat Enterprise Linux 7, even improves performance. He added that the flaw’s impact is moderate, in such that it is difficult to exploit but easy to fix.
