Local privilege escalation
Published Mar 10, 2026 · Updated Mar 10, 2026
External initialization of trusted data in Microsoft Entra login VM extension before 1.0.033370002 allows local users to elevate privileges. Microsoft has not published which trusted variable or data store is externally initialized, what input controls it, or the affected code path. Access to the Linux host is required, but no prior extension privilege or user interaction is required; successful exploitation grants control over protected host data and service operation.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
