The issue allows a local unprivileged user to instruct the root-owned udisks daemon to overwrite encryption metadata on block devices. This can permanently invalidate encryption keys and render encrypted volumes inaccessible. Successful exploitation results in a denial-of-service condition through irreversible data loss."}], "lastModified": "2026-03-02T08:15:57.953", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:redhat:enterprise_linux:10.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D65C2163-CFC2-4ABB-8F4E-CB09CEBD006C"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:freedesktop:udisks:2.0.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D31F1F1D-2E26-4D8E-A8C0-5395F302C444"}], "operator": "OR"}]}], "sourceIdentifier": "[email protected]"}
