Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Vulnerability in the MySQL Connectors product of Oracle MySQL (component: Connector/ODBC).   The supported version that is affected is 26.7.0. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where MySQL Connectors executes to compromise MySQL Connectors.  Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Connectors and  unauthorized read access to a subset of MySQL Connectors accessible data. CVSS 3.1 Base Score 6.8 (Confidentiality and Availability impacts).  CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H).

Comment 1 Michal Schorm 2026-10-24 20:06:48 UTC
The 26.10.0 release notes list only 2 bug fixes (Bug #40010434, Bug #39938996) — Oracle doesn't put CVE numbers in connector release notes, only in the CPU advisory.

The intermediate versions (26.7.0, 26.7.1) are also vulnerable.

26.10.0 should be compatible with both Server 8.4 and 9.7.
