CVE-2026-50367 is a Windows Sensor Data Service elevation of privilege vulnerability caused by incorrect access of an indexable resource (range error). It has a CVSS v3.1 base score of 7.8 (High) and a temporal score of 6.8. The attack vector is LOCAL, with LOW attack complexity, LOW privileges required, and no user interaction. Microsoft reports no public disclosure and no known exploitation, with exploit code maturity marked UNPROVEN. This is a local privilege escalation issue, so enterprise risk is primarily for systems where an attacker already has local access or can execute code on the host.

Highlights:
- CVSS scores: Base 7.8 - Temporal 6.8
- Exploit status & code maturity: Publicly Disclosed: No; Exploited: No; Exploit Code Maturity: UNPROVEN
- Impact: Elevation of Privilege; confidentiality, integrity, and availability impacts are all HIGH
- Exploitation likelihood: Exploitation Less Likely, with a LOCAL vector, LOW attack complexity, LOW privileges required, and no user interaction
- Severity for enterprise: High technical severity, but lower enterprise exposure than network-based issues because exploitation requires local access; higher concern on systems where untrusted local users or code execution are possible
- Patch status: available; customer action required
