Secure Boot bypass via undisclosed UEFI module flaw
Published Mar 14, 2023 · Updated May 5, 2025
Secure Boot bypass in Trend Micro Full Disk Encryption 6.0.0.3204 and earlier allows physically proximate attackers to bypass boot verification. Trend Micro identifies vulnerable UEFI modules that Microsoft planned to block through the Secure Boot DBX but does not disclose the validation defect. Exploitation requires physical access; bypass alone does not expose encrypted drive contents, but it enables follow-on attacks against the device.
