{"id":"DEBIAN-CVE-2022-31621","details":"MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_xbstream.cc, when an error occurs (stream_ctxt-\u003edest_file == NULL) while executing the method xbstream_open, the held lock is not released correctly, which allows local users to trigger a denial of service due to the deadlock. Note: The vendor argues this is just an improper locking bug and not a vulnerability with adverse effects.","modified":"2026-08-27T23:04:14.594550546Z","published":"2022-05-25T21:15:08.573Z","upstream":["CVE-2022-31621"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-31621"}],"affected":[{"package":{"name":"mariadb-10.5","ecosystem":"Debian:11","purl":"pkg:deb/debian/mariadb-10.5?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:10.5.15-0+deb11u1"}]}],"versions":["1:10.5.11-1","1:10.5.12-0+deb11u1","1:10.5.12-1","1:10.5.13-0+deb11u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-31621.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
