Severity by source
AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Local EoP requiring prior low-privileged code execution gives AV:L/PR:L; type confusion yielding SYSTEM justifies C:H/I:H/A:H with unchanged scope.

Access of resource using incompatible type ('type confusion') in Windows DWM allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Desktop Window Manager (DWM) Core Library allows an authenticated attacker to gain SYSTEM-level privileges by triggering a type-confusion (CWE-843) condition. The flaw affects a broad range of supported Windows client and server releases from Windows 10 1607 through Windows 11 26H1 and Windows Server 2016 through 2025. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already have authenticated, low-privileged local code execution on the target (CVSS PR:L, AV:L) - this is not remotely exploitable and cannot be triggered across the network or from an unauthenticated position. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H (7.8, High) is internally consistent with a local privilege-escalation flaw: local attack vector, low complexity, low privileges required (an authenticated user must already have code execution on the host), no user interaction, unchanged scope, and full confidentiality/integrity/availability impact consistent with a SYSTEM-level compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has already gained low-privileged code execution on a Windows host - for example via a phishing payload or a compromised standard user account - runs a crafted local program that drives DWM into the type-confusion condition to corrupt memory in the privileged compositor and elevate to SYSTEM. From there they disable security tooling, install persistence, and move laterally. … |
| Remediation | Patch available per vendor advisory: apply the Microsoft security update for CVE-2026-58541 for each affected SKU as listed in the MSRC update guide at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-58541; the exact per-version fixed build numbers should be taken directly from that advisory rather than assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: inventory all Windows 10 (1607-22H2), Windows 11, and Windows Server 2016-2025 systems to identify exposure scope. …
