CVE-2025-48505

Local privilege escalation via weak path permissions

Published Aug 11, 2026 · Updated Aug 11, 2026

Incorrect default permissions in AMD Unified Installer before 2026.1 allow local users to execute code with elevated privileges on Windows. AMD identifies weak permissions in the Vitis Unified installation path but has not disclosed the affected entries, access-control settings, or privileged loading sequence. Exploitation requires low-privileged local access, an attacker-controlled path modification, and active user interaction; successful abuse runs arbitrary code with elevated privileges.
