Can't really verify that it's off, though. That's switch for TPM features only. You cannot disable PSP as it is responsible for x86 initialization. Sounds like a job for refactoring.

In a report published last week, cybersecurity researchers disclosed a vulnerability in the driver that would allow attackers to steal sensitive information like passwords, and it impacts all Ryzen processors, as well as several previous AMD generations. Kyriakos Economou, co-founder of security research firm ZeroPeril, published a report last week that said non-privileged users could exploit the driver to access the sensitive information stored in memory, according to The Record. Originally, AMD listed the vulnerability as only affecting Ryzen processors. The report says that all desktop and mobile Ryzen processors are affected, and AMD has updated its security disclosure since. The exploit also allows attackers to get around mitigations like kernel address space layout randomization KASLR , which protect against attacks that exploit a known address for the kernel.

Windows 10 and Windows 11 report the same. I already did a complete reinstall. The Windows Device Manager shows no errors. When I switch back to my old Ryzen 5 everything works. Upgraded from X to X3D. EKCert is missing. I have this problem with Windows 10 latest official build and with Windows 11 fresh installed and updated. I found out that there is a service in the Task Planer that seems to be responsible to obtain this certificate. But it fails with different errors. After looking into this and based on the information you have provided, it seems that the issue may be related to the TPM firmware version not being compatible with the newer AMD Ryzen 7 x CPU. To troubleshoot this issue, you may want to try the following:. If it's not up to date, update the firmware to the latest version available on the motherboard manufacturer's website. Check for any conflicting settings: Ensure that there are no conflicting settings in the BIOS that could be causing the issue. For example, if there's an option to enable both the fTPM and the hardware TPM, try disabling one of them to see if it makes a difference.

Thank you.

I reset the Bios to factory optimized settings which on my board enables CSM and fTpm trying to reinstall windows I would get the same error, I attempted to install UEFI windows with fTmp enabled but leaving secure boot disabled CSM enabled, which is my motherboard optimized default and I just get a light blue screen with No error, but it just sits there and does nothing, after a while the PC shuts down. I reached out to Gigabyte and of course they tell me it is not their issue that fTpm is part of the CPU. I have tried all the troubleshooting steps suggested to me and nothing seems to work, I can either install windows 10 with the CSM enabled and fTpm enabled in a "legacy" bios or I can keep fTpm disabled and install windows 10 in UEFI mode secure boot but not both and both is needed for Windows I am not a total novice when it comes to computer repair, but this issue has me stumped. Could it be that the CPU is malfunctioning?

As a quick reminder, the purpose of PSB is to provide a hardware root-of-trust that will verify the integrity of the initial UEFI firmware phases, thereby preventing persistent firmware implants. In this part of the blog series, we will dig deeper into the nitty gritty details of PSB, including a first glimpse of how it works under the hood, how it should be configured and, naturally, how various major vendors fail to do so. For the sake of brevity, we won't go into detail on the purpose of each phase as it has already been widely covered already e. In order to understand the trust hierarchy in more depth, we will first take a look at how the UEFI firmware, stored in the SPI flash, is structured. Once again, for the sake of brevity, as the structure is relatively complex, we will only focus on portions relevant to the chain-of-trust.

Another day, another vulnerability. As reported by TechSpot , the flaw is in the driver for AMD Platform Security Processor PSP , and could leave systems vulnerable by allowing attackers to steal encryption keys, passwords, or other data from memory. This makes it a prime target for attacks. Operating at a low-level, entirely outside the purview of the main CPU and operating system, the PSP, like the IME, is often considered a potential backdoor into a machine. These subsystems allow sections of memory to be partitioned off and secured for special uses. However, these features have also proved to be subject to vulnerabilities too. The vulnerability is found in a range of AMD chipsets.

I reached out to Gigabyte and of course they tell me it is not their issue that fTpm is part of the CPU. Microsoft Tech Talks. You signed out in another tab or window. I have tried all these steps, nothing I do will allow both secure boot and fTpm to work together, which windows 11 states it requires, if I install windows with CSM enabled secure boot off and fTpm enabled it will install however in windows device security it does not show any manufacturing data, and the error it mentions the same that it cannot find information on the TPM, i click clear TPM and I don't think anything even happens to be honest as I am yet to receive a message at boot indicating fTpm was reset, I have also tried this in the Bios, same results or lack of. Because it's common, there are many reasons why the error might appear:. Just make sure both computers don't contain identical backdoors which is not that difficult. For discrete TPMs the specification explicitly says that they are not required to be resistant to physical attacks probably because that would require specifying what kinds of attacks it is supposed to be resistant to. The other one is that we keep this whole messy legacy. Those gigantic x86 Programmer's guide volumes I've yet to add to my bookshelf? Are you sure? Or on their car seat. I used to believe this kind of thing, but now I think you greatly underestimate human indifference and interest in effort conservation uncharitably called "laziness". Ahhh, okay.

The PSP has a 4. The PSP Key is also used to authenticate the processor to the operating system and other system components.

I'd had fTPM working just fine for ages when it suddenly went beserk because I'd accidentally disconnected a hard drive. Now it shall be high-performance, too? I completely understand why some people would want that, and develop it. Question Question Windows 10 and Office issues all related? At least the second part, the system of the two computers and the checker, is compared to even the very simplest parts of a modern computer laughibly simple. We just don't work at it. Meltdown is a different story since the CPU is supposed to be protecting that. You should upgrade or use an alternative browser. I believe it happens even before POST. Systems May 1, Aeacus. I've read that, several years ago, parts of the Russian security establishment switched to mechanical typewriters. It does some basic system initialization and then loads a public key from SPI attached flash memory.
