AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Local, low-privilege trigger with no user interaction; a kernel DirectX pointer dereference yielding code execution justifies S:C and full C/I/A impact.

Untrusted pointer dereference in Windows DirectX allows an authorized attacker to execute code locally.
AnalysisAI
Local code execution in the Windows DirectX graphics component (CVE-2026-50382) lets an already-authenticated user run arbitrary code and, because the CVSS scope is Changed, break out of the calling security context to compromise the wider system. It affects a broad range of Windows client and server builds from Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 through 2025. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already have local, authenticated access to the target Windows host at low privilege (PR:L) and the ability to execute code that reaches the DirectX component - consistent with AV:L (local) and AC:L (low complexity), with no user interaction needed (UI:N). … 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:C/C:H/I:H/A:H (8.8, High) describes a local attack (AV:L) requiring only low privileges (PR:L) and no user interaction, with a Changed scope and total confidentiality, integrity, and availability impact - the profile of a privilege-escalation / local code-execution flaw where a low-privileged user gains high-impact control over the system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A standard, non-administrative user (or malware running in a low-privileged context after initial access, e.g., via phishing or a compromised service account) executes a program that submits crafted input to the vulnerable DirectX component, causing it to dereference an attacker-controlled pointer. The resulting memory corruption is leveraged to execute code in a higher-privileged/kernel context, and the Changed scope means the attacker escapes their original sandbox to control the broader system. … |
| Remediation | Patch available per vendor advisory: apply the Microsoft security update for CVE-2026-50382 for your specific Windows build via Windows Update or WSUS/SCCM, using the guidance at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50382 (the input confirms a fix is available from the vendor but does not specify exact KB/build numbers, so map your SKU to the correct KB on that page). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 10 (build 1809+), Windows 11 (up to 26H1), and Windows Server 2019-2025 systems and identify which systems have local user access privileges. …
