CVE-2022-3675

Sažetak |
Fedora CoreOS supports setting a GRUB bootloader password
using a Butane config. When this feature is enabled, GRUB requires a password to access the
GRUB command-line, modify kernel command-line arguments, or boot
non-default OSTree deployments. Recent Fedora CoreOS releases have a
misconfiguration which allows booting non-default OSTree deployments
without entering a password. This allows someone with access to the
GRUB menu to boot into an older version of Fedora CoreOS, reverting
any security fixes that have recently been applied to the machine. A
password is still required to modify kernel command-line arguments and
to access the GRUB command line.
