CVE-2025-50096

Local server hang or repeatable crash

Published Jul 15, 2025 · Updated Jul 16, 2025

Denial of service in MySQL Server 8.0.0 through 8.0.42, 8.4.0 through 8.4.5, and 9.0.0 through 9.3.0 allows local users to hang or crash it. The flaw is in InnoDB, but Oracle has not published the affected code path or the operation that mishandles attacker-controlled input. Exploitation requires high privileges and a local logon to the host; success causes a server hang or repeatable crash without reported data disclosure or modification.
