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.","state":0,"publishedAt":"2022-11-23T00:00:00+00:00","modifiedAt":"2026-10-14T18:35:35.968+00:00","affected":[{"ecosystem":"Vendor product","name":"n/a","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"n/a\",\n                    \"product\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"version\": \"n/a\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[],"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/"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2022-45873","license":"CVE Program Terms of Use","key":"cve-program:CVE-2022-45873","identifiers":["CVE-2022-45873"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
