CVE-2023-31320Public exploitNetwork attack vector

Display corruption via Direct3D 11 driver input

Published Nov 14, 2023 · Updated Aug 2, 2024

Improper input validation in the AMD Radeon Graphics display driver allows attackers to corrupt the display and interrupt service. A public Windows proof of concept submits Direct3D 11 work to the driver and demonstrates display corruption, but the rejected input and faulty validation operation remain undisclosed. Execution requires an affected AMD graphics card and driver on a supported Windows host, and the demonstrated consequence is display disruption rather than data exposure or modification.
