CVE-2025-61662 is a use-after-free vulnerability in GRUB's gettext module. A missing command-unregistration call leaves the gettext command registered after its module is unloaded. Invoking the orphaned command accesses memory that is no longer valid, potentially crashing GRUB and causing denial of service. Confidentiality or integrity compromise is possible but has not been established.
