{"id":"CVE-2021-3979","details":"A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.","modified":"2026-05-15T12:04:20.608217768Z","published":"2022-08-25T20:15:09.473Z","related":["SUSE-SU-2022:2817-1","SUSE-SU-2022:2818-1","SUSE-SU-2022:4501-1","openSUSE-SU-2024:12195-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:fedoraproject:fedora:35:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:37:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"35"},{"last_affected":"37"}],"vendor_product":"fedoraproject:fedora"},{"cpes":["cpe:2.3:a:redhat:ceph_storage:3.0:*:*:*:*:*:*:*","cpe:2.3:a:redhat:ceph_storage:4.0:*:*:*:*:*:*:*","cpe:2.3:a:redhat:ceph_storage:4.3:*:*:*:*:*:*:*","cpe:2.3:a:redhat:ceph_storage:5.0:*:*:*:*:*:*:*","cpe:2.3:a:redhat:ceph_storage:5.1:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"3.0"},{"last_affected":"4.3"},{"last_affected":"5.1"},{"last_affected":"4.0"},{"last_affected":"5.0"},{"last_affected":"4.0"},{"last_affected":"5.0"}],"vendor_product":"redhat:ceph_storage"},{"cpes":["cpe:2.3:o:redhat:ceph_storage_for_ibm_z_systems:4.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"4.0"}],"vendor_product":"redhat:ceph_storage_for_ibm_z_systems"},{"cpes":["cpe:2.3:a:redhat:ceph_storage_for_power:4.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"4.0"},{"last_affected":"4.0"}],"vendor_product":"redhat:ceph_storage_for_power"},{"cpes":["cpe:2.3:a:redhat:openshift_container_storage:4.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"4.0"}],"vendor_product":"redhat:openshift_container_storage"},{"cpes":["cpe:2.3:a:redhat:openshift_data_foundation:4.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"4.0"}],"vendor_product":"redhat:openshift_data_foundation"}]},"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/09/msg00025.html"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2021-3979"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2024788"},{"type":"REPORT","url":"https://tracker.ceph.com/issues/54006"},{"type":"FIX","url":"https://github.com/ceph/ceph/commit/47c33179f9a15ae95cc1579a421be89378602656"},{"type":"FIX","url":"https://github.com/ceph/ceph/pull/44765"},{"type":"ARTICLE","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BPOK44BESMIFW6BIOGCN452AKKOIIT6Q/"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
