CVE-2022-31622 (GCVE-0-2022-31622)

Vulnerability from cvelistv5 – Published: 2022-05-25 00:00 – Updated: 2024-08-03 07:26 Disputed

Summary

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.

Severity

No CVSS data available.
