CVE-2026-101629
MediumCVSS 4.9Summary
A vulnerability in Oracle MySQL (InnoDB component) affects MySQL Server 9.7.0-9.7.3 and 26.7.0-26.7.1, and MySQL Cluster in the same versions. A high-privileged attacker with network access can cause a hang or frequently repeatable crash (complete DoS) of the server or cluster.
Risk Assessment
A high-privileged attacker can cause database unavailability, disrupting applications that depend on MySQL. Impact is limited to availability (CVSS 4.9).
Recommendation
Update MySQL Server and MySQL Cluster to the version containing Oracle's fix and restrict network access to the database for high-privileged accounts.
