A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled.","published":"2019-04-26T21:29:00.000Z","lastModified":"2026-06-17T02:35:43.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-268"],"affected":["systemd project/systemd","canonical/ubuntu linux","netapp/hci management node","netapp/snapprotect","netapp/solidfire","netapp/cn1610 firmware"],"epss":{"score":0.00915,"percentile":0.59887,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2019-04-26","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":46760,"kind":"exploit","title":"systemd - DynamicUser can Create setuid Binaries when Assisted by Another Process","url":"https://www.exploit-db.com/exploits/46760","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/dos/46760.txt","file":"exploits/linux/dos/46760.txt","published":"2019-04-26","added":"2019-04-26","updated":"2019-04-26","author":"Google Security Research","type":"dos","platform":"linux","port":null,"verified":true,"codes":["CVE-2019-3844","CVE-2019-3843"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://bugs.chromium.org/p/project-zero/issues/detail?id=1771"}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB (verified) and the impact is high, while EPSS rates exploitation at 0.9%.
