Windows Kernel Information Disclosure Vulnerability

Published Jul 14, 2026 CVSS 3.1 · 3.3 Low EPSS < 1% KEV · Not listed
Description
Exposure of sensitive information to an unauthorized actor in Windows Kernel allows an authorized attacker to disclose information locally.

Analysis

AI-generated

Technical impact

This vulnerability allows a local authorized attacker to read sensitive information that is normally protected by the Windows kernel. The flaw is an information disclosure flaw (CWE‑200). Because an attacker must already have some local privilege to exercise the vulnerability, the scope is confined to local systems.

Affected Systems

Microsoft Windows 10 versions 1607, 1809, 21H2, 22H2 and Microsoft Windows 11 versions 24H2, 25H2, 26H1, as well as Microsoft Windows Server releases from 2012 to 2025 (including core installations), are affected. All vulnerable editions run on the architectures listed in the CPE data, so both x86 and x64 machines are within reach.

Risk and Exploitability

The CVSS base score of 3.3 indicates a low severity overall, and the EPSS score is less than 1%, suggesting a very low probability of exploitation at this time. The vulnerability is not listed in the CISA KEV catalogue. An attacker would need local privilege and the opportunity to trigger the kernel code that leaks data, so the likelihood of a practical exploit is limited unless elevated privileges are already compromised.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the security update for CVE‑2026‑50419 released in the MSRC advisory.
  • Restrict privileged accounts to only those that need elevated permissions, limiting the pool of potential internal attackers.
  • Perform regular privilege reviews and audit user rights to ensure that only trusted accounts have local administrative access.
  • Monitor system logs for unusual kernel activity that might indicate exploitation attempts.
