CVE-2026-19546
8.8Red Hat · Red Hat Enterprise Linux
A code injection vulnerability exists within the DBI component of Red Hat Enterprise Linux, potentially allowing authenticated users to inject and execute arbitrary code.
Executive summary
A high-severity code injection vulnerability in the DBI component of Red Hat Enterprise Linux requires immediate attention to prevent unauthorized command execution.
Vulnerability
The flaw is an improper control of code generation (CWE-94) residing in the DBI (Database Interface) component. An attacker with low-level authenticated access can leverage this vulnerability to perform code injection, leading to high impacts on confidentiality, integrity, and availability.
Business impact
The CVSS score of 8.8 reflects the potential for severe system compromise. Because this vulnerability affects the core database interface, a successful exploit could allow an attacker to execute arbitrary code with the privileges of the database service, leading to total data exfiltration or system takeover.
Remediation
Immediate Action: Check the Red Hat Security Advisory (RHSA) portal for the latest security errata and apply the necessary patches for the DBI component.
Proactive Monitoring: Monitor database query logs for anomalous behavior or unexpected system calls originating from the database interface.
Compensating Controls: Apply principle of least privilege to database service accounts and ensure that database interfaces are not exposed to untrusted users or network segments.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
Organizations running Red Hat Enterprise Linux should immediately monitor Red Hat security bulletins for the specific patch release. Given the broad range of affected versions, patching should be treated as a high-priority maintenance task to secure the database layer against potential code injection attacks.
