What happened?

As far as I understand this topic, the latest Windows Update from August 13, 2024 did some changes to some UEFI tables so that there were signatures of vulnerable Shims blacklisted. Therefore, booting Ventoy now fails with the message

Verifying shim SBAT data failed: Security Policy Violation
Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation

This topic was already discussed for a supposedly earlier Shim version in #2692 which is still open for some reason. The recent issue was posted on forums here and here

As a temporary workaround, secure boot must be disabled until there is an updated version of ventoy with the latest Shim version available.

Edit: As pointed out by KevinLenoir, the target OS for SecureBoot can be changed from "Windows" to "Other OS" on Machines which support this feature. This way, Secure Boot might not have to be disabled completely.

More Information on how Shim works can be found on Arch Wiki. More info on the topic of SBAT revocation lists can be found in the rhboot/shim repository here and here

Same issue here. Seemed to have occurred randomly, it worked one week but failed the next. I have also tried formatting the USB and reinstalling Ventoy 1.0.99 again, no dice. Only thing that works is disabling secure boot. Restoring platform keys and bios CMOS resets do not seem to help.

I think it has something to do with recent sb-related updates to Windows? https://support.microsoft.com/en-us/topic/kb5025885-how-to-manage-the-windows-boot-manager-revocations-for-secure-boot-changes-associated-with-cve-2023-24932-41a975df-beb2-40c1-99a3-b3ff139f832d

Yep.

[Secure Boot Advanced Targeting (SBAT) and Linux Extensible Firmware Interface (EFI)] This update applies SBAT to systems that run Windows. This stops vulnerable Linux EFI (Shim bootloaders) from running. This SBAT update will not apply to systems that dual-boot Windows and Linux. After the SBAT update is applied, older Linux ISO images might not boot. If this occurs, work with your Linux vendor to get an updated ISO image.

Turning Secure boot off is only a workaround for now until a newer verison releases patching the previous fk up they had. Regards TechySkills

Issue is with secure boot patch issued by Microsoft. Need Ventoy update to correct the issue. Works if you disable secure boot, but negates using Ventoy for Windows 11 installs, unless you employ the system requirements bypass hack.

KevinLenoir commented 3 months ago

Hey ! Just found out that we might not need to disable the secure boot. In the bios, there was a setting about "Secure boot OS", which was either "Windows" or "Other OS". Turning this option to "Other OS" worked for me

Snoodking commented 3 months ago

Thanks for the info. Not all BIOS has that option, specifically OEM computers, like HP, Dell, etc.

don-dolarson commented 3 months ago

Is this really a problem created by Microsoft? I've installed Linux Mint 22 on my laptop (UEFI with Secure Boot enabled) a couple of days ago and there wasn't a single problem. I decided to reinstall the very same Mint today (again) using the same Ventoy stick with 1.0.96 on it and suddenly there is a shim problem this time. I haven't had anything with Microsoft to do. Wasn't even connected to the internet on this machine in like a half the year...

don-dolarson commented 3 months ago

Just updated Ventoy to the latest 1.0.99 on another Linux machine, booted Ventoy without the shim error, booted the very same Mint 22 live image on it.

Double checked with sudo mokutil --sb-state and indeed SecureBoot is enabled.

Don't know what's going on. The machine is a MSI laptop from 2013.

It seems to be specifically affecting Windows 11 users. Looks like Microsoft released a SHIM revocation update this month that caused the issues. If your PC was not running Windows 11, you wouldn't have received the revocation update. I don't believe this affected existing systems running Windows 10 either.

don-dolarson commented 3 months ago

The machine hasn't seen Windows in years but still I could see the same shim error described in this topic when tried to reinstall from Mint 22 to Mint 22 today using the same stick for both installations, hence why I'm here. It wasn't a problem for 3 days ago when I put that stick into the laptop and installed Mint 22 for the first time but today, I couldn't load Ventoy boot screen and the laptop shutdown after 3 seconds with the shim error before that. Updating the stick and Ventoy on it to the latest solved the problem for me but I was surprised that you blame Microsoft for this when the machine wasn't even been connected to the internet in more than 6 months. The last BIOS/UEFI update was done someday in 2015.

Strange situation.

Nope. Windows 10 user, this problem prevented my Ventoy USB from being booted on my PC. It worked fine on my Windows 11 laptop, but that's probably because it hasn't been turned on in a bit so didn't get the revoked SBAT update...

  1. According to the folder structure of this repo the Grub2 version is 2.04: GRUB2/MOD_SRC/grub-2.04
  2. According to MS they blocked all Grub2 versions affected by CVE-2022-2601. And the CVE says that all Grub2 version lower or equal to version 2.06 are affected.
  3. So I think the devs needs to update the Grub2 to a version newer than version 2.06.
postmaxin commented 3 months ago

So I think the devs needs to update the Grub2 to a version newer than version 2.06.

I took a quick look and it's not likely to be as simple as just dropping a new version in: the devs have also patched bits of grub-2.04 to suit Ventoy's needs -- lots of little changes.

Does this matter if grub is signed by MOK? According to my investigations, they blocked shim by SBAT policy, not grub. And if I replace shim with one which cames from Fedora (see comments in this issue: #2692) - it passes the check despite of old grub. This can be fixed quickly by replacing few signed files.

I don't know. Thought they blocked grub as bootloader in specific versions.

cvb011 commented 3 months ago

There is a way to reset Microsoft's new sbat policy to default (I'm currently using this way).

  1. Add this reg key to prevent Windows add flawed sbat policy: reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot\SBAT /v OptOut /d 1 /t REG_DWORD According to this post, it should fix the problem. If not, go forward.
  2. Disable Secure Boot then boot to RU (A CMOS edit toolkit)
  3. Press Alt + = and set all SbatLevelRT & SbatLevel data to 00
  4. Reboot and enable Secure Boot, the sbat policy will reset to system default

According to Microsoft's article, it has something to do with recent security updates to Windows.

Once the bios is updated all problems go away as I assume secure boot is fully reset and the update from MS no longer applies. So everyone update your bios or if you have the latest version reflash the same version it might help.

You should be able to reset SECURE BOOT configuration in UEFI. At the end you can also disable SECURE BOOT and just use linux as intended. I don't understand how that happen from the inside of the VM guest if this is what you are saying.

The update of Windows 10 in a VM running in a UEFI environment with Secure Boot enabled may have altered Shim or boot-related binaries, which should not directly affect the Linux host. However, if there is any state sharing between the VM and the host, this could have caused inconsistencies in the physical machine's Secure Boot. Furthermore, if the Linux host uses Secure Boot and relies on binaries like Shim, the VM update may have caused incompatibilities with SBAT or the binary signatures on the host. 🐣 🙄

https://arstechnica.com/security/2024/08/a-patch-microsoft-spent-2-years-preparing-is-making-a-mess-for-some-linux-users/

How I Solved my case:

  1. Disable Secure Boot in the BIOS
  2. Boot your Linux System
  3. Go to Terminal
  4. Commands:

sudo apt update sudo apt install --reinstall shim-signed grub-efi

*If not working, also try:

sudo mokutil –list-sbat-revocations sudo mokutil –set-sbat-policy delete sudo mokutil –list-sbat-revocations

To fix the virtual network of the virtualization ("Nertwork 'default' is not active"):

sudo virsh net-list -all sudoo virsh net-start default

g1ngernator commented 2 months ago

Same issue, I use my ventoy on constantly different devices so workarounds aren't really helpful.

nsi-test commented 2 months ago

The answer of RENANZG is really helpful! Here is how I do the similar thing. I disable secure boot, I boot from a live linux desktop (Ubuntu 24.04 in my case), I opened a terminal and typed (see his answer):

sudo mokutil –list-sbat-revocations sudo mokutil –set-sbat-policy delete sudo mokutil –list-sbat-revocations

The first and the last line are informative and they don't change. Then I do reboot and I REENABLE secure boot. After restart Ventoy is working on that machine.

May be

sudo apt update sudo apt install --reinstall shim-signed grub-efi

would help too, but I don't have a computer for now to test. Thank you RENANZG!

SagePtr commented 2 months ago

If you use single/few Ventoy USB dongle(s) on many different PCs, it's much better to upgrade Shim on Ventoy partition itself to solve the issue for your Ventoy instance, rather than do workaround on each target machine: https://github.com/ventoy/Ventoy/issues/2692#issuecomment-2031412234

Thank you very much @SagePtr, I found a "clean" computer to test. Your advice really works! With a "patched" Ventoy flash drive, it behaves as in normal situation. Thanks also to the original source - @onenowy . I highly recommend this variant.

Muzosh commented 2 months ago

So far, I have seen some solutions for this problem, but none of them are applicable when trying to install actual Windows. I have downloaded a W11 ISO from here (which pulls it from actual Microsoft repositories): https://msdl.gravesoft.dev/

Installed Ventoy to an USB stick, transferred the ISO on the stick and rebooted into BIOS, selected the stick and got the error.

Verifying shim SBAT data failed: Security Policy Violation
Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation

Is there a way to overcome this issue while trying to install Windows?

Disable Secure Boot in BIOS, boot from Ventoy, start Windows installation On first reboot, enable Secure Boot and continue Windows installation

digital-spinner commented 2 months ago

@Muzosh you can also reset the Secure Boot settings, keys, exclusions (Blacklist Database (DBX) stores certificates and SHA-256 hashes) whatever this option is available in your UEFI configuration to factory defaults. Probably you will need to re enable Secure Boot after that or change it's mode back to normal. If you are using custom mode than it's up to you to clear those added recently revocations so it won't bother Ventoy again. Basically it's all about to reset or clear the Blacklist Database (DBX) stores certificate for Secure Boot as far as I know.

Hi everyone,

To stop messing with EFI security, there is a solution from user Natsuru3 to try: an updated ventoy.disk.img.xz file with SHIM v15.8 > https://github.com/ventoy/Ventoy/issues/2692#issuecomment-2362323248

I quote:

Hi everyone. After reading over the about comments I decided to try to make this a little more user friendly. I ended up modifying the ventoy.disk.img.xz file with the new shim so that you can use the Ventoy2Disk to update your drives without the need to mount, copy and rename files. I have tested this with my MediCat USB in both MBR mode and GPT mode. It seems to be working for me. You are welcome to give this a try. Please let me know if it worked for you.

ventoy-1.0.99 - Updated (shim-x64-15.8-3.x86_64) - ventoy.disk.img.xz.zip

Actually, it works for me, at least to start Ventoy.

A (very) short test with a few ISOs:

Best regards, Johan
