Known Issue

After installing KB5041782, if you have enabled the dual-boot setup for Windows and Linux in your device, your device might fail to boot Linux and show the error message “Verifying shim SBAT data failed: Security Policy Violation. Something has gone seriously wrong: SBAT self-check failed: Security Policy Violation.”

The cause of the issue is that KB5041782 applies a Secure Boot Advanced Targeting (SBAT) setting to devices that run Windows to block old, vulnerable boot managers. This SBAT update will not be applied to devices where dual booting is detected.

However, on some devices, the dual-boot detection did not detect some customized methods of dual-booting and applied the SBAT value when it should not have been applied. As a result, the issue occurs.

To solve this issue, you can do as follows:

Step 1: ​Boot into your device’s firmware settings. Disable Secure Boot (steps vary by manufacturer).

Step 2: Delete SBAT update.

• ​Boot into Linux.
• ​Open the terminal and run the command: sudo mokutil –set-sbat-policy delete.
• ​Enter your root password if prompted.
• ​Boot into Linux once more.

Step 3: Verify SBAT revocations.

• ​In the terminal, run the command: mokutil –list-sbat-revocations.
• ​Ensure the list shows no revocations.

Step 4: Now, enable Secure Boot and boot into Linux. Run the command: mokutil –sb-state. The output should be “SecureBoot enabled”.

Step 5: Boot into Windows. Open Command Prompt as Administrator and run: reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecureBoot\SBAT /v OptOut /d 1 /t REG_DWORD. This will prevent future SBAT updates in Windows.
