CVE-2026-50382 is a DirectX Graphics Kernel untrusted pointer dereference vulnerability that can lead to remote code execution. Microsoft rates it with a CVSS v3.1 base score of 8.8 (High) and a temporal score of 7.7. The attack vector is LOCAL, with LOW attack complexity, LOW privileges required, NO user interaction, and CHANGED scope. Microsoft reports no public disclosure and no known exploitation, with exploit code maturity listed as UNPROVEN. Enterprise risk is primarily for systems where an attacker can obtain local guest VM access and then target the host OS; this is not a network-only exposure.

Highlights:
- CVSS scores: Base 8.8 - Temporal 7.7
- Exploit status & code maturity: Publicly Disclosed: No; Exploited: No; Exploit Code Maturity: UNPROVEN.
- Impact: Remote Code Execution with HIGH confidentiality, integrity, and availability impact.
- Exploitation likelihood: Exploitation Less Likely; the vector is LOCAL with LOW attack complexity, LOW privileges required, and NO user interaction.
- Severity for enterprise: High technical severity, but lower enterprise exposure than network-reachable flaws because exploitation requires local access; risk is more relevant in VM, host, or multi-tenant environments where untrusted local access may be possible.
- Patch status: available; customer action required.
