{"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":"2026-04-02T07:33:44.096928Z","published":"2022-08-25T20:15:09.473Z","related":["MGASA-2022-0138","SUSE-SU-2022:2817-1","SUSE-SU-2022:2818-1","SUSE-SU-2022:4501-1","openSUSE-SU-2024:12195-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/09/msg00025.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00034.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/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ceph/ceph","events":[{"introduced":"0"},{"last_affected":"457c145aefd30a852f525fbf76a871f676502c0a"},{"fixed":"47c33179f9a15ae95cc1579a421be89378602656"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"13.0"}]}}],"versions":["SES1-GM","SES1-maint01","agogpemikxte-build-me","mark-v0.70-wip","rrygrvmctuzz-build-me","ses2-gm","ses3-milestone4","ses3-milestone5","ses3-milestone6","ses5-deepsea-pr-test","ses5-gm","ses5-milestone10","ses5-milestone11","ses5-milestone12","ses5-milestone5","ses5-milestone6","ses5-milestone7","ses5-milestone8","ses5-milestone9","suse_hammer","suse_latest","v0.1","v0.10","v0.11","v0.12","v0.13","v0.14","v0.15","v0.16","v0.16.1","v0.17","v0.18","v0.19","v0.19.1","v0.2","v0.20","v0.20.1","v0.20.2","v0.21","v0.21.1","v0.21.2","v0.21.3","v0.22","v0.22.1","v0.22.2","v0.23","v0.23.1","v0.23.2","v0.24","v0.24.1","v0.24.2","v0.24.3","v0.25","v0.25.1","v0.25.2","v0.26","v0.27","v0.27.1","v0.28","v0.28.1","v0.28.2","v0.29","v0.29.1","v0.3","v0.30","v0.31","v0.32","v0.33","v0.34","v0.35","v0.36","v0.37","v0.38","v0.39","v0.4","v0.40","v0.41","v0.42","v0.42.1","v0.42.2","v0.43","v0.44","v0.44.1","v0.44.2","v0.45","v0.46","v0.47","v0.47.1","v0.47.2","v0.47.3","v0.48.1argonaut","v0.48.2argonaut","v0.48.3argonaut","v0.48argonaut","v0.49","v0.5","v0.50","v0.51","v0.52","v0.53","v0.54","v0.55","v0.55.1","v0.56","v0.56.1","v0.56.2","v0.56.3","v0.56.4","v0.56.5","v0.56.6","v0.56.7","v0.57","v0.58","v0.59","v0.6","v0.60","v0.61","v0.61.1","v0.61.2","v0.61.3","v0.61.4","v0.61.5","v0.61.6","v0.61.7","v0.61.8","v0.61.9","v0.62","v0.63","v0.64","v0.65","v0.66","v0.67","v0.67-rc1","v0.67-rc2","v0.67-rc3","v0.67.1","v0.67.10","v0.67.11","v0.67.2","v0.67.3","v0.67.4","v0.67.5","v0.67.6","v0.67.7","v0.67.8","v0.67.9","v0.68","v0.69","v0.7","v0.7.1","v0.7.2","v0.7.3","v0.70","v0.71","v0.72","v0.72-rc1","v0.72.1","v0.72.2","v0.73","v0.74","v0.75","v0.76","v0.77","v0.78","v0.79","v0.8","v0.80","v0.80-rc1","v0.80.1","v0.80.10","v0.80.11","v0.80.2","v0.80.3","v0.80.4","v0.80.5","v0.80.6","v0.80.7","v0.80.8","v0.80.8.1","v0.80.8.2","v0.80.8.4","v0.80.8.5","v0.80.9","v0.81","v0.82","v0.83","v0.84","v0.85","v0.86","v0.87","v0.87.1","v0.87.2","v0.88","v0.89","v0.9","v0.90","v0.91","v0.92","v0.93","v0.94","v0.94.1","v0.94.1.1","v0.94.1.2","v0.94.1.3","v0.94.1.4","v0.94.1.5","v0.94.1.6","v0.94.1.7","v0.94.10","v0.94.2","v0.94.3","v0.94.3.1","v0.94.3.2","v0.94.3.3","v0.94.4","v0.94.5","v0.94.6","v0.94.7","v0.94.8","v0.94.9","v10.0.0","v10.0.1","v10.0.2","v10.0.3","v10.0.4","v10.0.5","v10.1.0","v10.1.1","v10.1.2","v10.2.0","v10.2.01","v10.2.1","v10.2.10","v10.2.11","v10.2.2","v10.2.3","v10.2.4","v10.2.5","v10.2.6","v10.2.7","v10.2.8","v10.2.9","v11.0.0","v11.0.1","v11.0.2","v11.1.0","v11.1.1","v11.2.0","v11.2.1","v12.0.0","v12.0.1","v12.0.2","v12.0.3","v12.1.0","v12.1.1","v12.1.2","v12.1.3","v12.1.4","v12.2.0","v12.2.1","v12.2.10","v12.2.11","v12.2.12","v12.2.13","v12.2.14","v12.2.2","v12.2.3","v12.2.4","v12.2.5","v12.2.6","v12.2.7","v12.2.8","v12.2.9","v13.0.0","v9.0.0","v9.0.1","v9.0.2","v9.0.3","v9.1.0","v9.2.0","v9.2.1"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"3.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.3"}]},{"events":[{"introduced":"0"},{"last_affected":"5.1"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"5.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"5.0"}]},{"events":[{"introduced":"0"},{"last_affected":"4.0"}]},{"events":[{"introduced":"0"},{"last_affected":"35"}]},{"events":[{"introduced":"0"},{"last_affected":"37"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE
