This occurs in parse_elf_object in shared/elf-util.c. The exploitation methodology is to crash a binary calling the same function recursively, and put it in a deeply nested directory to make its backtrace large enough to cause the deadlock. This must be done 16 times when MaxConnections=16 is set for the systemd/units/systemd-coredump.socket file.","published_at":"2022-11-23T00:00:00Z","last_modified_at":"2026-10-14T19:16:54.910000Z","cvss_v3_score":5.5,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-400"],"nvd_references":["https://github.com/systemd/systemd/commit/076b807be472630692c5348c60d0c2b7b28ad437","https://github.com/systemd/systemd/pull/25055#issuecomment-1313733553","https://github.com/systemd/systemd/pull/24853#issuecomment-1326561497","https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MS5N5SLYAHKENLAJWYBDKU55ICU3SVZF/"],"vuln_status":"Modified","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-10-14T23:59:09.254433Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"fedoraproject","vendor_name":"fedoraproject","product_slug":"fedora","product_name":"fedora","version_start":"36","version_start_inclusive":true,"version_end":"36","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:o:fedoraproject:fedora:36:*:*:*:*:*:*:*"},{"vendor_slug":"systemd-project","vendor_name":"systemd_project","product_slug":"systemd","product_name":"systemd","version_start":"250","version_start_inclusive":true,"version_end":"251","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:systemd_project:systemd:*:*:*:*:*:*:*:*"},{"vendor_slug":"systemd-project","vendor_name":"systemd_project","product_slug":"systemd","product_name":"systemd","version_start":"252","version_start_inclusive":true,"version_end":"252","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:systemd_project:systemd:252:rc1:*:*:*:*:*:*"},{"vendor_slug":"systemd-project","vendor_name":"systemd_project","product_slug":"systemd","product_name":"systemd","version_start":"252","version_start_inclusive":true,"version_end":"252","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:systemd_project:systemd:252:rc2:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/systemd/systemd/commit/076b807be472630692c5348c60d0c2b7b28ad437","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/systemd/systemd/pull/25055#issuecomment-1313733553","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/systemd/systemd/pull/24853#issuecomment-1326561497","source_type":"PATCH","tags":["patch"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MS5N5SLYAHKENLAJWYBDKU55ICU3SVZF/","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2022-11-23T00:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:24:22.847249Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:24:22.847249Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:24:22.847249Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:21:33.515320Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:21:33.515320Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:21:33.515320Z","label":"SSVC decision revised","source":"vulnrichment"}]}
