Out-of-bounds read in Windows Management Instrumentation allows an authorized attacker to disclose information locally.
AnalysisAI
Out-of-bounds read in Windows Management Instrumentation (WMI) enables a locally authenticated, low-privileged attacker to disclose potentially sensitive information from process memory. Affecting a broad sweep of Windows client and server releases from Windows Server 2012 through Windows 11 26H1, the flaw is rooted in a memory safety defect in the WMI subsystem (CWE-125). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authorized local user account with low privileges on the target system - the CVSS PR:L metric confirms a standard (non-administrative) authenticated session is sufficient, and AV:L confirms local system access is mandatory with no network-based exploitation path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N yields a base score of 5.5 (Medium), accurately reflecting that exploitation is gated behind local access and a valid low-privilege account, which substantially narrows the realistic attack surface compared to network-exploitable flaws. … 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 | The primary remediation is to apply Microsoft's security updates, which resolve the out-of-bounds read across all affected Windows releases. … Detailed patch versions, workarounds, and compensating controls in full report. |
