AMD won't patch all chips affected by severe data theft vulnerability — Ryzen 3000, 2000, and 1000 will not get patched for 'Sinkclose'

  That’s so stupid, also because they have fixes for Zen and Zen 2 based Epyc CPUs available.

  Intel vs. AMD isn’t “bad guys” vs. “good guys”. Either company will take every opportunity to screw their customers over. Sure, “don’t buy Intel” holds true for 13th and 14th gen Core CPUs specifically, but other than that it’s more of a pick your poison.

      I’m waiting to see how DeepComputing’s RISC-V mainboard for the Framework turns out. I’m aware that this is very much a development platform and far from an actual end-user product, but if the price is right, I might jump in to experiment.

    How is AMD “screwing us over”? Surely they aren’t doing this on purpose? That seems very cynical.

      They are 100% intentionally not patching old chips intentionally by not allocating resources to it. It’s a conscious choice made by the company.

  Really not good enough from AMD. I wonder if Intel wasn’t a complete dumpster fire right now if they would still cut off the fix at Zen 3 (I doubt it). There’s really no reason not to issue a fix for these other than they don’t want to pay the engineers for the time to do it, and they think it won’t cost them any reputational damage.

  I hate that every product and company sucks so hard these days.

  source

  • kibiz0r@midwest.social ⁨2⁩ ⁨months⁩ ago

    They did issue a fix: “Buy a new CPU please!”

    That’s why they don’t mind the reputation hit. If 1 person swears allegiance to Intel as a result but 2 people buy new AMD chips, they’re still ahead. And people will forget eventually. But AMD won’t forget the Q3 2024 sales figures.

  I feel like this is the perfect place for Right to Repair legislation: the product is broken? And it’s outside your support window? Then give customers what they need to make the fix themselves. It’s not good enough to say “meh, guess you gotta buy one of our newer chips then 🤷”

    Consumer usage is not really concerned by the attack scenario of this vulnerability from what I understand. The prerequisite is to have access to the bios so it’s already game over at this point.

  How severe is this vulnerability?

  source

  • ducking_donuts@lemm.ee ⁨2⁩ ⁨months⁩ ago

    The good news is that in order to exploit the new vulnerability, the attacker first has to obtain kernel level access to the system somehow - by exploiting some other vulnerabilities perhaps.

    The bad news is once Sinkclose attack is performed, it can be hard to detect and mitigate: it can even survive an OS reinstall.

    source

    • scoutFDT@lemm.ee ⁨2⁩ ⁨months⁩ ago

    • JASN_DE@lemmy.world ⁨2⁩ ⁨months⁩ ago

      The other bad news: there are so many vulnerabilities on all systems which can be used to gain root-level access, it’s just a matter of time. Also, even future vulnerabilities will be an issue, as the underlying Sinkclose attacks will still work.

  AMD has unfortunately a long history of abandoning products before its reasonable on its graphics division. Its not really acceptable, up until earlier this year my NAS/server was running a 3600 and its only for power saving purposes I changed that as its still a very workable CPU in that role.

  I am getting so sick of all these BIOS updates because of all these security vulnerabilities all the time. It is so tiring having to set up my settings all over again all of the time.

    Back your settings up and restore them then.

    source

    • ipkpjersi@lemmy.ml ⁨2⁩ ⁨months⁩ ago

      Depending on your BIOS and/or motherboard, you can’t restore them between versions. The point of clearing the BIOS settings after flashing a new version is to ensure that you only have values that are expected.

  • ozymandias117@lemmy.world ⁨2⁩ ⁨months⁩ ago

    If an attacker gets access to your system, they will be able to ensure you can’t get rid of the vulnerability

    It will persist across operating system installs

    However, this requires them to get access first

  • psmgx@lemmy.world ⁨2⁩ ⁨months⁩ ago

    If they get root or admin they can hack the chip itself.

    But minor exploits, nada, no issue, you good. Gotta get root to make it happen.

    Problem is if you, as they say, get got, you have no way of knowing if they’re in your CPU, and no way to fix if they did – basically gotta trash it and replace.

  so that means you can internally flash the bios chip from the os?

  would be cool if there were coreboot builds for these platforms, this exploit seems pretty useful

  source

  • zer0squar3d@lemmy.dbzer0.com ⁨2⁩ ⁨months⁩ ago

    Wait yeah can someone explain why this exploit couldn’t be used to say rewrite it to support coreboot and turn this into a good thing?

    source

    • Jumuta@sh.itjust.works ⁨2⁩ ⁨months⁩ ago

      because you need the coreboot people to write firmware that can initialise the system, and that probably takes a lot of reverse engineering

      I don’t know much about this, but I assume there’s little to no effort for corebooting on the amd side, I’ve only seen intels platforms with coreboot sorry

    They aren’t patching CPUs that were released 5 years ago.

    They should be patching back to Ryzen 1 since those are still perfectly good CPUs. 5-7 years really isn’t that old considering how little improvement there is with each generation.

    source

    • RedWeasel@lemmy.world ⁨2⁩ ⁨months⁩ ago

      Sure, not much per gen, but if you compare say a 1700x vs the current 9700x, you are roughly looking at a 3x improvement in single and multicore performance increase.
