Exposure of sensitive system information to an unauthorized control sphere in Windows Win32K allows an authorized attacker to disclose information locally.
AnalysisAI
Sensitive kernel information is exposed to low-privileged local users through a CWE-497 flaw in the Windows Win32K graphics subsystem, confirmed by Microsoft's own security team (secure@microsoft.com). The scope-changed CVSS vector (S:C/C:H) indicates the leaked data originates from the kernel security boundary, making this a classic KASLR-defeat primitive that threat actors chain with separate privilege-escalation exploits to achieve full system compromise. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a locally authenticated session with at minimum standard-user (low) privileges, confirmed by the CVSS PR:L metric; unauthenticated or network-only exploitation is not possible (AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.6 (Medium) reflects that this is a local, authenticated, high-complexity information-only flaw - no direct code execution or data modification is possible through this CVE alone. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Microsoft cumulative updates that advance each affected release to or beyond its fixed build: Windows 10 22H2 to at least 10.0.19045.7725, Windows 11 24H2/25H2 to at least 10.0.26100.9445, Windows Server 2025 to at least 10.0.26100.33438, Windows Server 2022 to at least 10.0.20348.5622, Windows Server 2019 to at least 10.0.17763.9245, Windows Server 2016 to at least 10.0.14393.9512, Windows Server 2012 R2 to at least 6.3.9600.23397, and Windows Server 2012 to at least 6.2.9200.26349 - see the complete build matrix at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-69832. … Detailed patch versions, workarounds, and compensating controls in full report. |
