CVE-2024-28916

Local privilege escalation via improper link resolution

Published Mar 20, 2024 · Updated May 3, 2025

Link-following in Microsoft Xbox Gaming Services before 19.87.13001.0 allows local users to elevate privileges on Windows. Microsoft identifies improper link resolution before file access but has not published the affected file operation, path validation logic, or service interface. Exploitation requires local low-privileged access and can cross a security boundary to grant elevated access, with confidentiality, integrity, and availability consequences.
