German security researchers discovered a method that can be used to leak data from other virtual machines on a server with the AMD EPYC series. The "SEVered" attack abuses the AMD Secure Encrypted Virtualization (SEV) feature to extract all memory of a virtual machine in plaintext. Full details at The Register.
However, a technique dubbed SEVered can, it is claimed, be used by a rogue host-level administrator, or malware within a hypervisor, or similar, to bypass SEV protections and copy information out of a customer or user's virtual machine.
The problem, said Fraunhofer AISEC researchers Mathias Morbitzer, Manuel Huber, Julian Horsch and Sascha Wessel, is that 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.

Word is going around that Apple is working on a new device codenamed "Star". One of the first models is reportedly internally named N84, and 9 to 5 Mac speculates this could be the first ARM-based Mac, or the first iOS laptop.
There’s not much information on what the device could possibly be, but we do know that it has a touch screen, a sim card slot, GPS, compass, is water resistant and it also runs EFI. EFI (Extensible Firmware Interface) is the boot system used by Macs, which leads us to believe that the Star project could potentially be the first ARM-based Mac, with a ship date as soon as 2020.
Then again, other sources indicate it could be a new, low-cost phone. Would be interesting of it's indeed the former, but a new phone does seem more likely:

German tech site PC Games Hardware pulls our attention to the Computex 2018 website, which reveals NVIDIA will host several press events between June 4 and June 7.
One of the more interesting entries appears to be a "GeForce / Gaming" product briefing. This fuels speculation that NVIDIA may show off a new video card at Computex. We do not have certainty about this, one of the other rumors that's going around is that NVIDIA will merely show off some new displays, probably the 4K HDR G-SYNC models.

Industry sources told DigiTimes that more price hikes are ahead for silicon wafers. The pricing of blank wafers is estimated to increase a further 20 percent on average this year, after already witnessing a same size increase in 2017. The price uptrend is expected to carry into 2020 as production is having a hard time to keep up with growing demand.
The sources said silicon wafer prices began to rebound in the beginning of 2017 and picked up quarter by quarter in the year, bolstered by explosive increases in demand for wafers from automotive electronics, IoT, memory, AI, and cryptocurrency mining sectors. In addition, limited capacity expansions by the world's top five suppliers have turned the oversupply into shortfall, further driving up the quotes. The world's top five suppliers - Shin-Etsu, Sumco, GlobalWafers, Siltronic and SK Siltron - together command over 90% of the global silicon wafer supply.
More expensive wafers mean higher revenue and profits for wafer suppliers, but lower profitability for foundry houses and chip designers:
With the uptrend lingering for wafer quotes, Taiwan Semiconductor Manufacturing Company (TSMC) indicated earlier that its gross margin rate may fall by 0.5-1pp on price hikes in 2018, compared to a smaller drop of 0.2pp in 2017 made possible by the annual contract signed earlier with wafer suppliers.

Yesterday we saw the rollout of NVIDIA's GeForce 397.93 WHQL drivers. One of the changes tucked away in the release notes is the removal of the "Experience Improvement Program" from the NVIDIA Control Panel. As reported by AnandTech, this means the data collection/telemetry features are now back in the GeForce Experience tool, and are no longer a part of the standard display drivers:

Microsoft is blocking the installation of Windows 10 April 2018 Update on systems with Avast antivirus software.
Avast reports on its product forums that Microsoft temporarily disabled the updates. Other sources indicate Microsoft made the decision due to complaints about blank desktop screens with no icons. At the moment, it's unclear what's causing this issue, as Microsoft and Avast are unable to reproduce the problem.
Microsoft temporarily disabled the updates on version 1803 on PCs with Avast. We are working together with MS to find out the cause of this issue, but unfortunately right now neither MS nor us are able to reproduce the issue.
Avast users who wish to upgrade to the latest version of Windows will need to remove the software and wait for more news. Alternatively, you can delay the deployment of Windows 10 April 2018 Update

Intel published a specification sheet with more details about the upcoming Z390 chipset. The new chipset has the same number of PCIe lanes, but the specifications have somewhat changed. Another key change is the support for USB 3.1 Gen 2, you can find the full overview at VideoCardz. The launch date of the Z390 is unclear, perhaps we'll hear more at Computex:
Intel has not really made any official introduction of the new chipset. We are only finding this by browsing Intel website, which is quite odd. However, this could mean that Computex Z390 showcase might actually happen. The previous embargo date was set to September, but the recent announcement from AMD could have affected those plans.

Speaking to the Wall Street Journal, Sony revealed that the fifth-generation PlayStation console is still three years away from us. This means the company's update cycle is slowing down, a new PlayStation console typically took about six-to-seven years, and the current PlayStation 4 went on sale in 2013. So far, the PS4 has sold over 79 million units.
"We will use the next three years to prepare the next step, to crouch down so that we can jump higher in the future," said Tsuyoshi "John" Kodera, who took over last October.
Mr. Kodera spoke a day after Sony's new chief executive, Kenichiro Yoshida, released his first three-year business plan. It included a conservative forecast for the videogame business, seeing operating profit in the final fiscal year of the plan, ending March 2021, slightly lower than the $1.6 billion it made in the year ended March 2018.
This doesn't mean there won't be PS4 updates, but a completely new generation isn't expected until 2021.
