Researchers Uncover UEFI Secure Boot Bypass in 3 Microsoft Signed Boot Loaders,
A security feature bypass vulnerability has been uncovered in three signed third-party Unified Extensible Firmware Interface (UEFI) boot loaders that allow bypass of the UEFI Secure Boot feature.
« These vulnerabilities can be exploited by mounting the EFI System Partition and replacing the existing bootloader with the vulnerable one, or modifying a UEFI variable to load the vulnerable loader
