CVE-2026-25828 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. grub-btrfs through 2026-01-31 (on Arch Linux and derivative distributions) allows initramfs OS command injection because it does not sanitize the $root parameter to resolve_device(). NOTE: a third party reports "exploitation may not be feasible under normal conditions and may depend on specific implementation details within resolve_device.". EPSS estimates a 1.21% chance of exploitation in the next 30 days.
