AMD’s Epyc server chips utilize Secure Encrypted Virtualization (SEV) to automatically encrypt virtual machines on the fly while stored in memory, but researchers now say that they can get around it with a technique dubbed SEVer: “miscreants at the host level can alter a guest’s physical memory mappings, using standard page tables, so that the SEV mechanism fails to properly isolate and scramble parts of the VM in RAM“.
The latest rumor is from (yet again) coming from WCCFTech so please take it with a grain of salt, that AMD will make an AM4 socket which detects CPUs with more than 8 cores, Some voices even saying 12- and 16-core CPUs. WCCFTech mentioned “according to private conversations we’ve had with incredibly knowledgeable people in the industry the actual core count figure might be closer to 12 cores” and not the 16C/32T that we’re hearing with the latest rumors.
Seems it’s official, the new AMD Radeon RX 500 are listed on AMD’s website if you inspect the source code you see it lists the new series. The announcement page is still empty and acts like a placeholder.
A lot of speculation about AMD’s Vega 12 solution made the round over the last two weeks, some said Vega 12 isn’t Intel’s new GPU solution others have said it definitely gets integrated into Intel’s Kaby-Lake CPU in order to deliver the graphics. The secret seems now lifted and the rumors ended up wrong.
AMD responded in a community post what’s really behind the claims from CTS-Labs – AMD makes it very clear that the issues identified by CTS-Labs research have very less to do with Meltdown & Spectre security holes, but there also telling us that these are associated with the firmware that manages the AMD Secure Processor (PSP) – similar to Intel’s ME. The chipset used in some AM4 and TR4 motherboards as well as others are getting a firmware patches (BIOS updates) for this.
The user emissary42 leaked yesterday night some new layout pictures on the german Hardware Luxx forum. The pictures showing the upcoming ASUS AMD X470 motherboard in details among all specifications.
The AMDFlaws.com story is over, it seems that it was a failed try to manipulate the stock market but besides this shameless try CTS-Labs still has some valid information to offer, and it shows that ASMedia-USB-3.x controller have several security flaws which allows attackers to abuse those controllers to deliver their keyloggers or malware code.
AMDFlaws.com reports multiple flaws regarding to AMD CPU’s. The question is if the page can be trusted as source? I believe so and take it serious but want to add right here and now that I have my doubts about the entire background of this story.
AMD released their roll out schedule for 2018, which affects Desktop systems and mobile systems. There is nothing much to show here since the changes to the new Ryzen CPU’s and are marginal, some boosts here and small improvements there.
