Seems a vulnerability has been found in everyone’s favourite bootloader <https://arstechnica.com/information-technology/2020/07/new-flaw-neuters-secure-boot-but-theres-no-reason-to-panic-heres-why/> which allows a bypass of the “Secure Boot” mechanism in modern UEFI-based machines. But given that so many other bypasses already exist, nobody seems especially worried about this. For example, the article references an attempt by Microsoft to revoke the certification of (an obsolete version of) a secure bootloader from Kaspersky Lab with a vulnerability in it; the revocation caused so many headaches for users that it had to be rolled back.
