AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions MariaDB Server versions prior to 10.6.3

Description The issue is related to the use of memory after it has been freed in the Binary string::free buffer() function of the MariaDB component /sql/sql string.h. This can be exploited by a remote attacker to cause a denial of service.

Recommendations For MariaDB Server versions prior to 10.6.3, update to a version 10.6.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the Binary string::free buffer() function until a patch is available.
