Have You Patched Flaws in Your Microprocessor Chips — New Business Risk

Raspberry Pi not vulnerable to Meltdown or Spectre bugs

Microchip flaw is far from Intel's only problem

In light of this, Apple advised users not to download apps from sources they cannot trust.

Also, Google has released a new stable build for Chrome OS, the operating system carried by a number of laptops and other computing devices in the market that opted not to go with the more standard Windows software.

True, vulnerabilities in chip design are rare.

HPE doesn't say much.

There's been some speculation regarding the updates that will protect PC users against these bugs and a potential impact on performance of their PCs. Data is supposed to be protected and isolated, but researchers discovered that in some cases, the information can be exposed while the processor queues it up. Almost everyone will be affected in one way or another.

Fears that the fixes would limit the performance of processors have largely been resolves. Malicious apps can exploit these methods to grant other parties unrestricted access to a system.

It's an industry technique used to optimize the processor's performance.

El Reg: "Can you explain why?"

El Reg: "Why would your software be less affected?" And this is independent of whether or not the device has been manufactured by Apple, Samsung, Lenovo, Dell, or you have built up your device yourself. "However, detection would have an extremely negative impact on the device's performance and significantly influence user experience; it would be a less effective approach than prevention".

El Reg: "Will NVMe be more or less impacted?"

What Meltdown and Spectre do?

El Reg: "So syscall-heavy offerings will suffer more?" Second, the patches being circulated reportedly slow down a machine by as much as 30%.

El Reg: "What will be the effect of implementing the fixes?" These are processors made my Intel, AMD, and ARM. Analogous to the idea behind KPTI, Microsoft is separating NT kernel memory, to address the problems. The vast majority should fall into this category.

"Therefore, we recommend that ESET users keep track of any related patches for their systems and apply them as soon as possible". ThreatModeler™ then empowers enterprise IT organizations to map their unique secure requirements and policies directly into their enterprise cyber ecosystem - providing real-time situational awareness about their current threat portfolio and risk conditions.

The company hasn't released an official statement yet but a spokesman said that the company is working hard to solve the issue. But the whole episode still sucks for admins, who now need to look at their environments from top to bottom for security issues.

The 31-year-old information security researcher and post-doctoral fellow at Austria's Graz Technical University had just breached the inner sanctum of his computer's central processing unit (CPU) and stolen secrets from it.

Scale helps justify the massive investment needed to develop improved semiconductor technology and produce chips. This led to the soaring of AMD's stock sometimes last week.
