This flaw stems from a programming error where the gettext command remains registered in memory after its module is unloaded. An attacker can exploit this condition by invoking the orphaned command, causing the application to access a memory location that is no longer valid. An attacker could exploit this vulnerability to cause grub to crash, leading to a Denial of Service. Possible data integrity or confidentiality compromise is not discarded. ## Affected - `grub2 <= 2.14` ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges. ## Vendor advisories - **RHSA-2026:5233** · Red Hat · fixed in: Red Hat Enterprise Linux Server (v. 7 ELS), Red Hat Enterprise Linux Server Optional (v. 7 ELS) · released 2026-03-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:5233) - **RHSA-2026:6492** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.12 · released 2026-04-09 · [advisory](https://access.redhat.com/errata/RHSA-2026:6492) - **RHSA-2026:7239** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.13 · released 2026-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:7239) - **RHSA-2026:15087** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.14 · released 2026-05-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:15087) - **RHSA-2026:14773** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.15 · released 2026-05-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:14773) - **RHSA-2026:10097** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.16 · released 2026-04-30 · [advisory](https://access.redhat.com/errata/RHSA-2026:10097) - **RHSA-2026:17596** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.17 · released 2026-05-20 · [advisory](https://access.redhat.com/errata/RHSA-2026:17596) - **RHSA-2026:5127** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.18 · released 2026-03-25 · [advisory](https://access.redhat.com/errata/RHSA-2026:5127) - **RHSA-2026:7243** · Red Hat · fixed in: Red Hat OpenShift Container Platform 4.19 · released 2026-04-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:7243) - **RHSA-2026:4652** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS EUS (v. 10.0) · released 2026-03-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:4652) - **RHSA-2026:4649** · Red Hat · fixed in: Red Hat Enterprise Linux BaseOS (v. 10) · released 2026-03-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:4649)
