CVE-2026-101637
Description
A flaw was found in MySQL's InnoDB component. A high-privileged remote attacker with network access can exploit this vulnerability to cause the server to hang or crash repeatedly, resulting in a Denial of Service (DoS). Additionally, exploitation can allow unauthorized data modification, enabling the attacker to insert, update, or delete certain database records.
Statement
This vulnerability is rated with Moderate severity for Red Hat deployments because successful exploitation demands high administrative privileges, substantially constraining the blast radius. Although the issue resides in the core InnoDB storage engine and could allow an authenticated attacker to trigger an instance crash or unauthorized data modifications, untrusted or unauthenticated network users cannot exploit it directly. Furthermore, supported Red Hat Enterprise Linux releases do not include the vulnerable upstream code.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
