It carries a CVSS 3.1 base score of 4.9 with an availability impact only and stems from an input or state condition that the server fails to handle safely under certain network requests.
A high-privileged attacker who already possesses network access via multiple protocols can trigger the flaw to force the MySQL Server into a hang or repeated crash, producing a complete denial-of-service condition. No authentication beyond the required high privileges is needed, and the attack does not require user interaction.
Vendor and distribution advisories, including those from Debian, Fedora, and NetApp, direct administrators to apply the corresponding MySQL updates that address the issue in the affected releases.
The associated EPSS score has remained flat at 0.0698 with no material rise after disclosure, and no reports of in-the-wild exploitation have surfaced in the referenced sources.
