An out-of-bounds read in the Network Device Enrollment Service (NDES) allows an attacker to trigger a crash of the NDES process. This weakness is a buffer read overrun (CWE-125). The vulnerability does not provide elevated privileges or access to sensitive data; its primary consequence is a denial of service that disrupts certificate enrollment for network devices.

Microsoft Windows 10 version 1607, Windows 10 version 1809, Windows Server 2012, Windows Server 2012 (Server Core), Windows Server 2012 R2, Windows Server 2012 R2 (Server Core), Windows Server 2016, Windows Server 2016 (Server Core), Windows Server 2019, Windows Server 2019 (Server Core), Windows Server 2022, Windows Server 2025, and Windows Server 2025 (Server Core) are impacted. The list also includes the specific Microsoft architectures referenced in the CNA data.

The vulnerability is scored 7.5 on CVSS, indicating a high impact and moderate to high complexity. EPSS score of 1% indicates a low but measurable exploitation probability, while the attack vector is inferred to be network-based, requiring access to the NDES endpoint and not requiring authentication. If exploited successfully, repeated crashes can exhaust system resources and deny legitimate users service availability. The vulnerability is not listed in CISA KEV, but its scope and impact warrant prompt patching.
