Official 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().
Technical Analysis
CVE-2026-25828 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2026-25828. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
