Recommendation: Monitor — no exploitation signal at the moment.

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."
