Out-of-bounds read in Windows Kernel allows an unauthorized attacker to disclose information over a network.
AnalysisAI
Remote information disclosure in the Microsoft Windows Kernel (CWE-125 out-of-bounds read) lets an unauthenticated attacker read kernel memory over a network, per the CVSS AV:N/PR:N vector, affecting a broad range of Windows 10, Windows 11, and Windows Server 2016 through 2025 builds. The flaw carries high confidentiality impact (C:H) with a minor availability side effect and no integrity impact, scoring CVSS 8.2. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Per the CVSS vector (AV:N/AC:L/PR:N/UI:N), no special conditions and no authentication or user interaction are required - an unauthenticated remote attacker can trigger the out-of-bounds read over a network against affected default Windows Kernel builds. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals point to a real, prioritizable issue rather than a paper high-CVSS finding. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with network reachability to a vulnerable Windows host sends a crafted request to the affected kernel-facing service, triggering an out-of-bounds read that returns adjacent kernel memory in the response. The leaked data - potentially pointers or secrets - can be harvested to bypass KASLR or stage a follow-on exploit. … |
| Remediation | Patch available per vendor advisory: apply the Microsoft security update for CVE-2026-50429 referenced at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50429, selecting the cumulative update matching each affected build (Windows 10 1607-22H2, Windows 11 24H2-26H1, and Windows Server 2016-2025 including Server Core); take exact patched build numbers from the MSRC page rather than assuming them. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit all Windows 10, 11, and Server 2016-2025 systems in your environment and prioritize remediation for systems with network exposure or running security-sensitive workloads. …
