AI Analysis
Technical Summary
This vulnerability (CVE-2026-35424) is classified as CWE-401, indicating a missing release of memory after its effective lifetime in the Windows Internet Key Exchange (IKE) Protocol on Windows 10 Version 1607 (build 10.0.14393.0). The flaw allows an unauthenticated attacker to remotely cause a denial of service by triggering memory exhaustion. The CVSS v3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and an impact limited to availability (denial of service). Microsoft has published an official fix for this vulnerability.
Potential Impact
An attacker can exploit this vulnerability remotely without authentication to cause a denial of service condition by exhausting memory resources in the IKE protocol implementation. This impacts system availability but does not affect confidentiality or integrity.
Mitigation Recommendations
An official fix is available from Microsoft. Users and administrators should apply the security update provided in the Microsoft advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-35424 to remediate this vulnerability.
