AI Analysis

Impact

The vulnerability involves an InnoDB storage engine defect that can be triggered by a high privileged attacker with network access over one or more MySQL protocols. When exploited, the server or cluster can hang or crash, resulting in a denial of service. The compromise does not affect confidentiality or integrity; the impact is limited to availability.

Affected Systems

Oracle MySQL Server versions 8.4.0‑8.4.12, 9.7.0‑9.7.3, 26.7.0‑26.7.1 and Oracle MySQL Cluster versions 8.0.0‑8.0.49, 8.4.0‑8.4.12, 9.7.0‑9.7.3 and 26.7.0‑26.7.1 are affected. The flaw resides in the InnoDB component of both products.

Risk and Exploitability

The CVSS base score of 4.9 reflects a moderate availability impact. The EPSS score is less than 1% (approximately 0.00422), indicating a low probability of exploitation. The vulnerability is not listed in CISA’s KEV catalog. The attack requires network connectivity and high privileges, limiting the potential spread. Public exploitation status is not specified, but the potential for repeated crashes underscores the importance of patching or operational safeguards.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the Oracle MySQL update that addresses the affected releases for Server and Cluster; consult Oracle’s security alert for the correct patch.
  • Restrict network access to MySQL ports to trusted hosts using firewalls or network segmentation to mitigate the high‑privileged attack requirement.
  • Deploy a high‑availability or fail‑over solution and monitor for repeated crashes, using automated restart scripts or clustering tools to reduce downtime.
