CVE-2023-31366

Service interruption via invalid-address write

Published Aug 13, 2024 · Updated Aug 14, 2024

Improper input validation in AMD μProf Tool before 3.4.494 allows local users to interrupt service through an invalid-address write. AMD has not disclosed the affected component or the input path that accepts the address; its bulletin states only that validation permits a write to an invalid address. Low privileges and local access are required, and the published impact is limited to loss of availability rather than data exposure or modification.
