Protected-memory corruption via improper ASP quantity validation
Published Feb 11, 2025 · Updated Feb 12, 2025
Out-of-bounds write in the ASP in affected AMD graphics products allows privileged local users to corrupt protected memory. AMD has not disclosed the ASP interface or input field whose quantity is insufficiently validated before the write exceeds its permitted bounds. Exploitation requires high local privileges and high-complexity conditions, and can compromise confidentiality, integrity, or availability beyond the vulnerable component.
