When GRUB is set to automatically decrypt disks using keys stored in the TPM, it reads the decryption key into system memory. If an attacker with physical access can corrupt the underlying filesystem superblock, GRUB will fail to locate a valid filesystem and enter rescue mode. At this point, the disk is already decrypted, and the decryption key remains loaded in system memory. This scenario may allow an attacker with physical access to access the unencrypted data without any further authentication, thereby compromising data confidentiality. Furthermore, the ability to force this state through filesystem corruption also presents a data integrity concern." } ], "affected": [ { "versions": [ { "status": "affected", "version": "0", "versionType": "semver", "lessThanOrEqual": "2.12" } ], "packageName": "grub2", "collectionURL": "https://www.gnu.org/software/grub/", "defaultStatus": "unaffected" }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 10", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "grub2", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:10" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 7", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "grub2", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:7" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 8", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "grub2", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:8" ] }, { "vendor": "Red Hat", "product": "Red Hat Enterprise Linux 9", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "grub2", "defaultStatus": "affected", "cpes": [ "cpe:/o:redhat:enterprise_linux:9" ] }, { "vendor": "Red Hat", "product": "Red Hat OpenShift Container Platform 4", "collectionURL": "https://access.redhat.com/downloads/content/package-browser/", "packageName": "rhcos", "defaultStatus": "affected", "cpes": [ "cpe:/a:redhat:openshift:4" ] } ], "references": [ { "url": "https://access.redhat.com/security/cve/CVE-2025-4382", "tags": [ "vdb-entry", "x_refsource_REDHAT" ] }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2364416", "name": "RHBZ#2364416", "tags": [ "issue-tracking", "x_refsource_REDHAT" ] }, { "url": "https://gitweb.git.savannah.gnu.org/gitweb/?p=grub.git;a=blobdiff;f=grub-core/kern/rescue_reader.c;h=a71ada8fb7da2eae6ee7135fe234fb1755ca78b0;hp=4259857ba9eea45446bc40ea13c3de4ab1b88ffd;hb=c448f511e74cb7c776b314fcb7943f98d3f22b6d;hpb=4abac0ad5a7914dd3cdfff08aaac06588bf98d80" } ], "datePublic": "2025-05-08T23:59:00.000Z", "problemTypes": [ { "descriptions": [ { "cweId": "CWE-306", "description": "Missing Authentication for Critical Function", "lang": "en", "type": "CWE" } ] } ], "x_redhatCweChain": "CWE-306: Missing Authentication for Critical Function", "workarounds": [ { "lang": "en", "value": "No mitigation is currently available that meets Red Hat Product Security’s standards for usability, deployment, applicability, or stability." } ], "timeline": [ { "lang": "en", "time": "2025-05-06T14:24:53.960Z", "value": "Reported to Red Hat." }, { "lang": "en", "time": "2025-05-08T23:59:00.000Z", "value": "Made public." } ], "providerMetadata": { "orgId": "53f830b8-0a3f-465b-8143-3b8a9948e749", "shortName": "redhat", "dateUpdated": "2026-06-30T10:40:11.899Z" }, "x_generator": { "engine": "cvelib 1.8.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2025-05-09T13:23:09.759013Z", "id": "CVE-2025-4382", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-05-09T13:33:37.385Z" } } ] } }
