> doing so (pressing backspace for 28 times in a row) for builds utilizing the ubiquitous Grub2 bootloader -- that's to say just about all of them -- immediately bypasses the lock screen, initiates the "Grub rescue shell" and grants the user access to the system for whatever nefarious things they have in mind.
笑出声 hhhhhh

没见过谁用 grub 加密码的。不过这个漏洞还是蛮搞笑的。

能不标题党么。昨天就看到了，对绝大多数用户来说根本无关紧要。更何况这属于 grub 的漏洞。

这漏洞纯属有病…… grub 有几个加密码的，按 E 直接在后面加个 single 连 root 都能拿到……
