I just saw an article on ZDNet (link) about Microsoft accidentally leaking the key to Secure Boot. Secure Boot is supposed "to ensure that each component of the boot process is signed and validated" and it prevents users from booting other operating systems. Using the key, a malicious person could install onto Windows operating systems computers or devices, other operating systems or a rootkit or bootkit. Microsoft in the meantime has already released two patches to try to fix this issue, and a third is expected.
