Name of the Vulnerable Software and Affected Versions MariaDB Server versions prior to 10.7

Description The issue is related to a denial of service vulnerability. In the extra/mariabackup/ds compress.cc file, when an error occurs while executing the create worker threads method, the held lock is not released correctly, allowing local users to trigger a denial of service due to a deadlock. The vendor considers this an improper locking bug rather than a vulnerability with adverse effects.

Recommendations For versions prior to 10.7, update to version 10.7 or later to resolve the issue. As a temporary workaround, consider disabling the create worker threads method in the extra/mariabackup/ds compress.cc file until a patch is available. Restrict access to the ds compress.cc module to minimize the risk of exploitation.
