CVE-2025-48511

Host crash via unchecked physical-address write

Published Nov 24, 2025 · Updated Nov 24, 2025

Improper offset validation in AMD uProf before 5.0 allows local users to crash the host by writing to a physical address. AMD has not identified the affected function or input field; the published mapping indicates that an index, position, or offset is not validated before the physical-address write. Low privileges and no user interaction are required, and the reported consequence is limited to a host crash or service interruption.
