AI Analysis

Impact

The flaw is an out‑of‑bounds read in the Network Device Enrollment Service (NDES), classified as CWE‑125. It can cause the service to crash, which leads to a denial of service condition that disrupts network connectivity for applications that rely on NDES.

Affected Systems

It relates to several Microsoft Windows platforms, including Windows 10 versions 1607 and 1809, and Windows Server versions 2012, 2012 R2, 2016, 2019, 2022, and 2025, both standard and Server Core installations. The vulnerability is present in both 32‑bit and 64‑bit builds as indicated by the CPE data.

Risk and Exploitability

The CVSS score of 7.5 signifies high severity. The EPSS score of 1% indicates a low but non‑zero probability of exploitation, and the advisory notes that it is not listed in the CISA KEV catalog. The likely attack path is over the network; an unauthenticated adversary can send crafted requests that trigger the out‑of‑bounds read, causing NDES to crash and produce a denial of service.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Microsoft security update for CVE‑2026‑96861 through Windows Update or the Microsoft Update Catalog.
  • If NDES is not required for your environment, disable the service to eliminate the attack surface.
  • Configure firewall rules to restrict inbound access to the NDES endpoints to only trusted hosts and monitor for repeated service crashes.
