Ok, so these "AMD flaws" are nowhere near anything like Meltdown or Spectre.
According to their "whitepaper", it lets you pwn your PSP and chipset if you already have root access on the main CPU. In the worst case, it's like the Intel ME BUP bug from december.
It's useful for researchers, coreboot porting, breaking DRM, etc. But it's no use for a remote (or even unprivileged local) attacker.
Their website makes it look way more dangerous than it is.
Then there's a lot of fishy stuff, like
- too much effort went into the website's design
- the website has lots of infographics and not-very-specific text, repeating the same things over and over again
- the whitepaper doesn't look like a whitepaper, and seems to be written with non-technical people in mind, especially the first few pages
- they have a huge legal disclaimer that says they may have financial interest in the value of AMD shares
- cts-labs.com exists for less than 1 year
@samis the only place I've seen this is cnet. And I don't know if that means 24h from yesterday to releasing the "whitepaper", or from today to releasing full details.
If the latter, then yeah, reasonable my ass, but also not really harmful unless you run random programs as root, or flash a BIOS from a sketchy russian site.
If the former, then it's not a disclosure from the security POV, only from PR POV, which makes it look even more awful.
