CVE-2026-33824

Double · Windows IKE Extension

A double-free vulnerability in the Windows IKE Extension may allow an unauthorized attacker to execute code over a network.

Executive summary

A critical double-free vulnerability within the Windows IKE Extension poses a severe risk of remote code execution.

Vulnerability

This is a memory corruption vulnerability involving a double-free error within the IKE Extension. This flaw allows an unauthenticated, remote attacker to trigger memory management errors, potentially leading to arbitrary code execution.

Business impact

The ability for an unauthenticated attacker to execute code over a network creates a high risk of remote system compromise. With a CVSS score of 9.8, this vulnerability is extremely critical and could be leveraged for widespread network infiltration or system instability. Immediate action is required to prevent unauthorized access to affected infrastructure.

Remediation

Immediate Action: Consult the official vendor security advisory to identify the affected versions and apply the necessary security updates or configuration changes.

Proactive Monitoring: Monitor network traffic for anomalous IKE protocol packets that may indicate exploitation attempts.

Compensating Controls: Implement network-level access controls to restrict access to IKE services to only authorized, trusted IP addresses, effectively isolating the vulnerable component.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Due to the critical nature of this remote code execution vulnerability, administrators must verify the status of their IKE implementations immediately. Ensure all security patches are applied as soon as they are made available by the vendor to mitigate this significant network-level threat.
