CVE-2023-31348

Local privilege escalation via DLL search-path hijacking

Published Aug 13, 2024 · Updated Aug 14, 2024

DLL hijacking in AMD μProf Tool and AMD uProf before 3.4.494 allows local users to escalate privileges and execute arbitrary code. AMD has not identified the executable, library name, or search-path operation that permits the DLL hijack. Exploitation requires local low-privileged access and user interaction; a planted library runs with elevated privileges and can fully compromise the host.
