Phoronix: Intel's Linux Graphics Driver Gets Patched For A Gen9 Graphics Vulnerability

On top of the Intel graphics driver patches back from November for denial of service and privilege escalation bugs, the Linux kernel received a new patch today for "CVE-2019-14615" regarding a possible data disclosure with Gen9 graphics hardware...

Last of the Gen9 gpu line is Comet Lake(and Whiskey Lake prior to it, which came after Coffee Lake afaik). Whatever happened to Gen10 graphics though? Just like Windows skipping a 9th version..

10 was Cannonlake.

forcibly clearing the EU state on each context switch sounds expensive - I assume there will be a short article benchmarking it Michael ?

If it is, hopefully there's a way to disable it. Local access exploits don't bother me as much for personal machines, especially if there is notable perf regression from their fixes.

Ah, that was short lived. Thanks

well if it can be exploited via a web browser you might just need to have it enabled all the time.

come to think of it, it probably has a hit on energy usage as well.

Gen9 benchmarks underway...
