Assigner: MITRE

Description
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."

Executive Summary

This vulnerability exists in grub-btrfs versions through 2026-01-31 on Arch Linux and derivative distributions. It allows an attacker to perform OS command injection during the initramfs phase because the software does not properly sanitize the $root parameter passed to the resolve_device() function.

Impact Analysis

An attacker exploiting this vulnerability could inject arbitrary operating system commands during the early boot process (initramfs). This could lead to unauthorized code execution, potentially compromising system integrity and security.
