UEFI Secure Boot

Over 290 MSI motherboards are reportedly affected by an insecure default UEFI Secure Boot setting settings that allows any operating system image to run regardless of whether it has a wrong or missing signature.
This discovery comes from a Polish security researcher named Dawid Potocki, who claims that he did not receive a response despite his efforts to contact MSI and inform them about the issue.
