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.

    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.

              You were misrepresenting things. Your needs have nothing to do with things not being functional. Something can be perfectly functional and not meet someones needs. Nobody said you should buy it as an investment.

                My interpretation was by far the most generous to your position, because it’s the only way it’s coherent.

                If people bought [this hardware that doesn’t actually provide anything anyone can realistically use at a reasonable price] it might eventually not suck. That’s treating a current purchase as an imaginary investment in maybe eventually being able to buy something useful.

                  You’re entitled to your opinion, I guess.

                  hardware that doesn’t actually provide anything anyone can realistically use

                  at a reasonable price

                  Thats completely arbitrary. If a price is reasonable or not depends on many factors. Obvious oversymplification.

                  That’s treating a current purchase as an imaginary investment in maybe eventually being able to buy something useful.

                  This shows that you have no idea what you are talking about. Small companies and open source projects depend on people buying their products instead of cheaper, sometimes better performing products of big conglomerates for other reasons than price alone.

          That’s not what I was referring to. I was referring to the act of “adding vulnerabilities”. Surely they aren’t doing that on purpose. And surely they would add fixes for it if it was economically viable? It’s a matter of goodwill and reputation, right?

          I don’t know, I just don’t think it’s AMD’s business model to “screw over” their customers. I just don’t.

            What I mean by that is that they will take a huge disservice to their customers over a slight financial inconvenience (packaging and validating an existing fix for different CPU series with the same architecture).

            I don’t classify fixing critical vulnerabilities from products as recent as the last decade as “goodwill”, that’s just what I’d expect to receive as a customer: a working product with no known vulnerabilities left open. I could’ve bought a Ryzen 3000 CPU (maybe as part of cheap office PCs or whatever) a few days ago, only to now know they have this severe vulnerability with the label WONTFIX on it. And even if I bought it 5 years ago: a fix exists, port it over!

            I know some people say it’s not that critical of a bug because an attacker needs kernel access, but it’s a convenient part of a vulnerability chain for an attacker that once exploited is almost impossible to detect and remove.

              Maybe they’ll reverse course with enough blowback, they did that once with ryzen already, don’t remember which Gen it was but it wasn’t going to be backwards compatible with certain type of mobos, but then they released it anyway and some mobo manufacturers did provide bios updates to support it.

              Similarish situation could happen here, the biggest hangup I’d think is that the 3000 series is nearly 5 years old, and getting mobo manufacturers on board for that could be difficult.

            No they are just choosing not to roll out the fix to a known issue, which is screwing customers over on purpose (to increase profits). It’s not a matter of goodwill, they sold a product that then turned out to have a massive security flaw, and now they don’t want to fix even though they absolutely could.

              I’m guessing it’s a balance between old products, effort, severity, etc. As we’ve learned, this is only an issue for an already infected system. 🤷‍♂️

                Ryzen 3000 series CPUs are still sold as new, I even bought one six months ago, they’re no where near being classified as “old”, they’re hardly 5 years old. And this is not only an issue for already infected systems because uninfected systems will intentionally be left vulnerable.

            No, but those vulnerabilities where there when you bought it.

            Would a car have a defect that was shown 5 years later, then the manufacturer would have to recall it or offer a repair program and or money in exchange.

            Since everything is proprietary you cannot even fix things like this by yourself. The manufacturer needs to be held liable.

              I mean… A car is different, depending on the defect. It’s like “this window only breaks if you’ve already crashed the car”. (The defect only causes a vulnerability if the system is already compromised AFAICT.) And 5 years is much, much younger for a car compared to a CPU, but that’s not the important bit, I know.

              But I agree with you all, I am not saying it shouldn’t be fixed, I was just saying I don’t think AMD is looking to screw over their customers on purpose. That’s all.

                “this window only breaks if you’ve already crashed the car”

                No, it’s usually more like “this thing will break and cause a car crash” or “this thing will murder everyone in the vehicle if you crash”. And companies still will not fix it. Look at the Ford Pinto, executives very literally wrote off people’s deaths as a cost of doing business, when they’d turn into fireballs during even low speed rear-end collisions. Potentially burning down the car that hit them too.

                Edit: I mean, just look at the Takata airbag recall. 100 million airbags from 20 different carmakers recalled because they wouldn’t activate during a crash.

                  When I said “It’s like”, I meant it as a simile to what’s going on with AMD right now. Not with what’s actually going on with car companies. Car companies are a whole different topic and discussion, of which I know nothing.

            The cost isn’t that high. They’re already doing it for a bunch of parallel systems.

            In a just world they’d be legally required to provide the fixes, or fully refund the entire platform cost. It’s not remotely ethical to allow this to exist unpatched anywhere, regardless of support life.

    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.

      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.

        They are doing similar stuff with deliberately delaying Linux driver capabilities for Radeon 7xxx series, to make more GPUs die out faster, by overheating (zero RPM fan until 60°+).

    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.

        This sounds weird. I was in the impression that operating systems load updated cpu microcode at every boot, because it does not survive a power cycle, and because the one embedded in the BIOS/UEFI firmware is very often outdated. But then how exactly can a virus persist itself for practically forever?

          The OS can’t get to the point of loading cpu microcode without that outdated, embedded microcode. The reason it can persist is because there aren’t a lot of good ways to see what that UEFI microcode actually is once it’s installed. Plus, only the UEFI tells you that it has successfully updated itself. There is no other more authoritative system to verify that against. So the virus could just lie and say it’s gone and you would never know. Hence needing to treat it as the worst case scenario, that it never leaves.

        And that introduces a specific type of supply chain threat: someone who possesses a computer can infect their own computer, sell it or transfer it to the target, and then use the embedded microcode against the target, even if the target completely reformats and reinstalls a new OS from scratch.

        That’s not going to affect most people, but for certain types of high value targets they now need to make sure that the hardware they buy hasn’t already been infected in the supply chain.

      It’s important because it allows them to directly modify the CPU’s microcode. Basically, the CPU has its own set of instructions, called microcode, which controls how the chip functions on a physical level. If they manage to change your microcode, even a full system reformat won’t kill the virus; You’ll need to either re-flash the CPU (which is not something the standard user or even power user will know how to do) or replace the entire CPU.

      I personally agree. I think it’s being somewhat overhyped. If step one is physical access to get things rolling… like for sure some machines are in more public areas than others. But for me, someone would have to break into my house first, then access my machine, just to run exploits later. The exploit is pretty massive, but I think needs to be tempered with “first they need physical access”. Because physically controlling machines has always been number 1 for security.

    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.

        Chip makes should not only treat customer CPUs as possibly-business hardware when adding shit like (Intel) ME, Pluton and (AMD) PSP, but also when patching serious vulnerabilities and providing support!

          When you pay for enterprise equipment, you are typically paying a premium for longer, more robust support. Consumer products are less expensive because they don’t get this support.

            But they are already pretending for whatever reason that these are suitable for enterprises, by always includingthe aformentioned remote control components!

          Agreed, firmware security by chip manufacturers has been underwhelming to say the least and we can blame them for that. But in this specific instance I still don’t see the benefit of a fix for consumer usage. Companies have a responsibility and accountability toward their users, so a fix is due, for personal laptops/PCs the threat is toward the owners themselves (activists, diplomats, journalists, etc.). The latter do not buy second hand equipment, and if the firmware is compromised while they own it, they are already in danger.

            You are assuming activists are well funded in some way, and that they are not repressed.

            This obviously has a benefit for consumer usage too, same as encryption. You’re basically saying consumers don’t need any kind of antivirus either, because it’s not that critical.
            This vuln should have been fixed for consumer hardware too, because it basically permanently taints all hardware that is vulnerable to it. And what makes it so hard to release patches for consumer hardware, when patches were already made for the same generations of enterprise hardware? Basically the majority of the work has been done already

              I’m not saying this is a small issue and nothing should be done. I just noted that the issue is not as big as some other hardware-based vulnerabilities we encountered in the past. And every threat model calls for a corresponding counter-measure.

              You are assuming activists are well funded in some way, and that they are not repressed. I’m assuming they are repressed, which is why they have people that buy and configure their equipment and hand it to them so that it hasn’t been tampered with. If you cannot afford that your should use your computer as if it was compromised.

              You’re basically saying consumers don’t need any kind of antivirus either Where did I write that?

              And what makes it so hard to release patches for consumer hardware. AMD focusing on where its money’s at and OEM/motherboard manufacturers being cheap and lazy and not pushing forward updates when they have them.

      Any news on the “pro” line? They were installed on business PCs and had additional security features built in. For instance there is a 3600 pro model.

        I dont know.

        If I had my choice between a CPU that has a vulnerability that can only be exploited if the system is already compromised

        or a CPU that are full of oxidation cancer, or frying themselves and doing irreparable damage… Which the company is being excessively shady about concretely admitting to any RMA promises and wwill all eventually die in short order…

        I think I’m gonna go with the Ryzen and not leave leave my computer outside at defcon.

          Sure but we’re talking about several generation old CPUs: nothing’s wrong with Intel’s 10/9/8th gen CPUs, which would be the contemporary ones to the Ryzen chips in question.

            How is that? Does risc-v have magical properties that make its designers infallible, or somehow make it possible to fix flaws in the physical design after the CPU has already been fabbed and sold?

              Because it does not set in stone that there can be only 2 companies producing compatible chips, which can be however bad until both of them does the same shit practices.

              So the short answer is by not stifling competition.

            As much as I like RISC-V, it is kind of ironic to suggest RISC-V ist the solution to this. At least as it stands, because of RISC-V’s simplicity, most if not all current RISC-V CPUs don’t even run microcode, so there is nothing to update/fix in case of a CPU bug. There’s even a very current example of this problem with that chinese RISC-V cpu that has this “GhostWrite” bug that allows every unpriviliged process to gain root access.

              As I said in an other reply, RISC-V is not the solution for the reason that they are perfect today. It is because it is not limited to being used by a few megacorporations that do whatever they want, but it allows competition where companies do what they need to become and remain a good choice.

                I understood that. My point was rather that in this particular case (a CPU bug that could be fixed via microcode, but AMD chose not to do so for certain CPUs), RISC-V wouldn’t have been of any advantage, because there would be nothing to fix in the first place. Sure, one could introduce microcode for RISC-V and people have argued in favor of doing so for this exact reason, but the architecture was intentionally designed to not require microcode.
