CVE-2024-49504

Encrypted disk disclosure through GRUB shell access

Published Nov 13, 2024 · Updated Nov 13, 2024

Improper access control in GRUB2 on openSUSE Tumbleweed before 2.12-28.1 allows physically proximate attackers to read encrypted disk files. SUSE has not published the responsible function or the access-control operation that fails inside the GRUB shell. Physical access and entry to the GRUB shell are required; the demonstrated consequence is disclosure of files protected by disk encryption.
