Product:
Windows TCP/IP
Summary
Use after free in Windows TCP/IP allows an unauthorized attacker to execute code over a network. This vulnerability can lead to significant impacts on confidentiality, integrity, and availability. Attackers can exploit this flaw without requiring any user interaction or special privileges.
Details
| Severity | Base Score | CVE |
|---|---|---|
| HIGH | 8.1 | CVE-2026-40415 |
Exploitation
To exploit this vulnerability, an attacker must craft a malicious network packet that triggers the use after free condition in the Windows TCP/IP stack. Once the condition is met, the attacker can execute arbitrary code on the affected system, potentially gaining control over it. The high attack complexity indicates that the attacker must have a good understanding of the network protocols involved.
Affected Products
- Windows TCP/IP: Vulnerable to unauthorized code execution due to use after free condition.
Mitigation
To mitigate this vulnerability, users should apply the latest security updates provided by Microsoft. Regularly updating systems and monitoring network traffic can help reduce the risk of exploitation. Additionally, implementing network security measures can help detect and block malicious packets.
