CVE-2022-21535

User-assisted local partial denial of service

Published Jul 19, 2022 · Updated Sep 24, 2024

Denial of service in Oracle MySQL Shell 8.0.28 and earlier allows local users to partially interrupt the client through user interaction. Oracle identifies the Shell General/Core Client component but has not published the flawed operation or untrusted input that triggers it. Exploitation requires logon access to the host and interaction by another person; the reported consequence is limited to partial availability loss.
