Security: Updates, Spectre/Meltdown and Why Not to Install Software Packages From the Internet

Revised Patches Out For New Kernel "mitigations=" Option For Toggling Spectre/Meltdown [Ed: Profoundly defective chips aren't being recalled/replaced (or even properly fixed). All the cost is being passed to the victim, the client, who should instead be compensated. Corporate greed has no bounds. They also hide NSA back doors in these chips. Imperial.]
The effort to provide a more convenient / easy to remember kernel option for toggling Spectre/Meltdown mitigations is out with a second revision and they have also shortened the option to remember.
See the aforelinked article if the topic is new to you, but this is about an arguably long overdue ability to easily control the Spectre/Meltdown behavior -- or configurable CPU mitigations in general to security vulnerabilities -- via a single kernel flag/switch. For the past year and a half of Spectre/Meltdown/L1TF mitigations there has been various different flags to tweak the behavior of these mitigations but not offering a single, easy-to-remember switch if say wanting to disable them in the name of restoring/better performance.

Someone from the Internet has told you not to execute random scripts you find on the Internet and now you're reading why we shouldn't install software packages from the Internet. Or more specifically, the aim of this article is why it's wise to stick to distribution maintained packages and not those latest software packages we find out there on the Internet even if it's distributed by the official brand's page.
However, it's okay to download software packages that are not available on the distribution repository but not vice versa. Read on below to learn more about why.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
