A moderate severity vulnerability was found in the InnoDB component of MySQL. An easily exploitable flaw allows a high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks can result in a hang or frequently repeatable crash (complete denial of service) of MySQL Server, as well as unauthorized update, insert, or delete access to some MySQL Server accessible data. Red Hat rates this flaw Moderate impact with a CVSS 3.1 score of 5.5 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H), matching the upstream Oracle severity rating. MySQL as shipped in Red Hat Enterprise Linux 8, 9, and 10 is affected; because MySQL is maintained upstream, a fix is being pursued through Oracle's upstream updates that Red Hat ships. The mysql package in Red Hat Enterprise Linux 6 Extended Lifecycle Support is not affected because the vulnerable code is not present. Fedora also ships affected mysql8.0 and mysql8.4 packages, which are handled through the community update process.
