Hi, you probably saw this flaw that seems to be present on all Dell machines >= 2009.
https://www.dell.com/support/kbdoc/000186019/dsa-2021-088-dell-client-platform-security-update-for-dell-driver-insufficient-access-control-vulnerability it is not entirely clear if BIOS itself is flawed, but - the phrase " insufficient access control vulnerability" - a new BIOS update on April 27 suggest that a bit. Do you have some more detailed information? If so, it touches many qubes users as well, which brings me to a more general question: Updating BIOS seems, generally, a security nightmare. Running untrusted software from an untrusted OS on an USB-key enhances likelihood of an evil-maid attack, and, worse, you are the maid ! I am curious on your comments / help suggestions.
