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."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/systemd/systemd/commit/076b807be472630692c5348c60d0c2b7b28ad437"},{"url":"https://github.com/systemd/systemd/pull/25055#issuecomment-1313733553"},{"url":"https://github.com/systemd/systemd/pull/24853#issuecomment-1326561497"},{"name":"FEDORA-2022-ef4f57b072","tags":["vendor-advisory"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MS5N5SLYAHKENLAJWYBDKU55ICU3SVZF/"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T14:24:03.197Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/systemd/systemd/commit/076b807be472630692c5348c60d0c2b7b28ad437","tags":["x_transferred"]},{"url":"https://github.com/systemd/systemd/pull/25055#issuecomment-1313733553","tags":["x_transferred"]},{"url":"https://github.com/systemd/systemd/pull/24853#issuecomment-1326561497","tags":["x_transferred"]},{"name":"FEDORA-2022-ef4f57b072","tags":["vendor-advisory","x_transferred"],"url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MS5N5SLYAHKENLAJWYBDKU55ICU3SVZF/"}]},{"problemTypes":[{"descriptions":[{"type":"CWE","cweId":"CWE-400","lang":"en","description":"CWE-400 Uncontrolled Resource Consumption"}]}],"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":5.5,"attackVector":"LOCAL","baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","integrityImpact":"NONE","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"NONE"}},{"other":{"type":"ssvc","content":{"timestamp":"2025-04-25T18:19:29.226607Z","id":"CVE-2022-45873","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-04-25T18:19:52.554Z"}}]}}
