Shuttle: Information on "Meltdown" and "Spectre"

Mobile devices are even more vulnerable to Meltdown and Spectre than computers OS fragmentation means that many devices won’t be patched

Google explained that "every Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013)".

A Democratic U.S. lawmaker asked Intel Corp and two other microchip makers on Tuesday to provide a briefing on the recently detected Spectre and Meltdown security flaws that could allow hackers to steal information from most computers and devices.

Microsoft is today rolling out new cumulative updates for three versions of Windows 10 operating system to include fixes for devices getting into unbootable state.

"While the firmware updates are effective at mitigating exposure to the security issues, customers have reported more frequent reboots on firmware updated systems", Shenoy said in a blog post.

An analysis of 100,000 United Kingdom corporate-owned and managed mobile phones and tablets has revealed that only 4% have security updates for the Meltdown and Spectre exploits and 24% can not be updated due to the age of the device. But older processors, lacking these newer features, will be significantly burdened and system performance will suffer under some workloads. They are similar in the sense that they exploit flaws in CPU architecture dating back decades to extract user information both from local applications on a device or, in the case of Spectre, from websites through a web browser.

Durbin said Monday the White House should release whatever recording it might have of the meeting. President, did you say that you want more people to come in from Norway?" a reporter asked.

"We have received reports from a few customers of higher system reboots after applying firmware updates", Shenoy said in a January 11 blog post.

Intel has already said that it believes that there are other options that will mitigate the performance drop, most notably Google's Retpoline patch, which is said to have an nearly zero impact. Shenoy also notes that these patches will have an impact on performance, at least based on their data center tests.

Patching: Performance ImpactTested: Server platforms running two-socket Intel Xeon Scalable systems (code-named Skylake), which is Intel's latest server microarchitecture. "For example, there are other mitigations options that could yield less impact".

The furore around the Meltdown and Spectre processors security flaws can be confusing, but the InSpectre app is here to help.
