A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

Here we are - 3600 which was still under manufacture 2-3 years ago are not get patched. Shame on you AMD, if it is true.

Attackers need to access the system kernel to exploit the Sinkclose vulnerability, so the system would have to already be compromised. The hack itself is a sophisticated vector that is usually only used by state-sponsored hackers, so most casual users should take that into account.

So it's a vulnerability that requires you to.already have been compromised. Hardly seems like news.

I can understand AMD only patching server chips that by definition will be under greater threat. On the other hand it's probably not worth the bad publicity not to fix more.

The reason that this is news is because it allows malware to embed itself into the processor microcode once kernel is breached. IE: If it is exploited for compromise, you either have to have the knowledge and hardware to reset the processor microcode manually (Requires an SPI flash tool) or you toss the hardware entirely. There's no just 'blow the drive away and reinstall the OS' solution available.

I don’t think it gets to the microcode but the UEFI.
