CVEID: CVE-2018-12127
Microarchitectural Load Port Data Sampling (MLPDS): Load ports on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

CVEID: CVE-2018-12130
Microarchitectural Fill Buffer Data Sampling (MFBDS): Fill buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

CVEID: CVE-2019-11091

I have to check these. since asus send the meupdate (12.0.35.1427) on 2019-05-14 with bios 2019/05/09 i will dig a little if i can find something I will added here.

BUT! in order to load these to the CODEXI for example. it has to have OEM main drivers. so far is ok. If these is new and most CVE patch are for xenon CPU the one of consumer is low level o medium. Let see is help desk push new drivers ASAP since are needed.
Learn, Play Enjoy! We help and collaborate, NOT complain!

j am sure your Processor is still invulnerable until asus release new bios with correct firmware.
All most intel processors with asus machines are vulnerable.
my processor too is affected.
