{"id":"UBUNTU-CVE-2022-31622","details":"** DISPUTED ** MariaDB Server before 10.7 is vulnerable to Denial of Service. In extra/mariabackup/ds_compress.cc, when an error occurs (pthread_create returns a nonzero value) while executing the method create_worker_threads, 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and not a vulnerability with adverse effects.","modified":"2022-05-25T21:15:00Z","published":"2022-05-25T21:15:00Z","withdrawn":"2025-06-23T15:55:03Z","references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-31622"},{"type":"REPORT","url":"https://jira.mariadb.org/browse/MDEV-26561?filter=-2"},{"type":"REPORT","url":"https://github.com/MariaDB/server/commit/e1eb39a446c30b8459c39fd7f2ee1c55a36e97d2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-31622"}],"affected":[{"package":{"name":"mariadb-10.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/mariadb-10.0"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.0.20-0ubuntu0.15.04.1","10.0.22-0ubuntu1","10.0.23-1","10.0.23-2","10.0.24-7","10.0.25-0ubuntu0.16.04.1","10.0.27-0ubuntu0.16.04.1","10.0.28-0ubuntu0.16.04.1","10.0.29-0ubuntu0.16.04.1","10.0.31-0ubuntu0.16.04.2","10.0.33-0ubuntu0.16.04.1","10.0.34-0ubuntu0.16.04.1","10.0.36-0ubuntu0.16.04.1","10.0.38-0ubuntu0.16.04.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-31622.json"}},{"package":{"name":"mariadb-10.1","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/mariadb-10.1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.1.25-1","1:10.1.29-6","1:10.1.34-0ubuntu0.18.04.1","1:10.1.38-0ubuntu0.18.04.1","1:10.1.38-0ubuntu0.18.04.2","1:10.1.40-0ubuntu0.18.04.1","1:10.1.41-0ubuntu0.18.04.1","1:10.1.43-0ubuntu0.18.04.1","1:10.1.44-0ubuntu0.18.04.1","1:10.1.47-0ubuntu0.18.04.1","1:10.1.48-0ubuntu0.18.04.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-31622.json"}},{"package":{"name":"mariadb-10.3","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/mariadb-10.3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:10.3.17-1","1:10.3.18-1","1:10.3.19-1","1:10.3.21-2","1:10.3.22-1","1:10.3.22-1ubuntu1","1:10.3.25-0ubuntu0.20.04.1","1:10.3.29-0ubuntu0.20.04.1","1:10.3.30-0ubuntu0.20.04.1","1:10.3.31-0ubuntu0.20.04.1","1:10.3.32-0ubuntu0.20.04.1","1:10.3.34-0ubuntu0.20.04.1","1:10.3.37-0ubuntu0.20.04.1","1:10.3.38-0ubuntu0.20.04.1","1:10.3.39-0ubuntu0.20.04.2"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-31622.json"}},{"package":{"name":"mariadb-10.6","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/mariadb-10.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:10.6.7-2ubuntu1","1:10.6.7-2ubuntu1.1","1:10.6.11-0ubuntu0.22.04.1","1:10.6.12-0ubuntu0.22.04.1","1:10.6.16-0ubuntu0.22.04.1","1:10.6.18-0ubuntu0.22.04.1"],"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-31622.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
