Local code execution via shader-controlled array index
Published Apr 23, 2024 · Updated Nov 4, 2025
Out-of-bounds write in AMD Software: Adrenalin and PRO Edition drivers allows local users to execute code via a malformed DirectX 11 shader. In atidxx64.dll shader processing, an array index is read directly from attacker-supplied bytecode and later used to calculate a write address without a bounds check. Low-privilege local access and an affected AMD graphics configuration are required; the controlled write corrupts driver-process memory and can execute code in that context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
