'Over 290 MSI motherboards are reportedly affected by an insecure default UEFI Secure Boot setting that allows any operating system image to run regardless of whether it has a wrong or missing signature. From a report:

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. The issue, according to Potocki, impacts many Intel and AMD-based MSI motherboards that use a recent firmware version, affecting even brand-new MSI motherboard models.'
