CVE-2026-101612
Description
A flaw was found in the MySQL InnoDB component. A local, highly privileged attacker with access to the underlying infrastructure, requiring interaction from another user, can exploit this vulnerability to cause a hang or repeatable crash. Successful exploitation results in a Denial of Service (DoS) of the database service.
Statement
This vulnerability is evaluated with a Moderate impact for Red Hat products because an attacker must already have local logon privileges on the host system and social engineering or human interaction is required to trigger the failure. Under standard database deployments, the flaw solely affects availability by terminating or hanging the daemon, with no compromise of data confidentiality or integrity. Consequently, the severe prerequisites and localized blast radius prevent direct remote exploitation across typical environments.
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.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart
While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, an attacker can still cause a denial of service if they can trigger an assert statement, and if the scope of the assert() extends beyond the attacker's own session. For example, if a server handles multiple simultaneous connections, if an assert() occurs in one single connection that causes all other connections to be dropped, this could be a significant denial of service.
