Device code execution via command-interface out-of-bounds write
Published Jul 1, 2026 · Updated Jul 1, 2026
Out-of-bounds writes in the command interface of NVIDIA ConnectX and BlueField firmware allow local users to execute device code. The interface writes beyond its intended buffer when it processes crafted input, corrupting device memory within the command-handling path. Exploitation requires local-host access to a virtual function, and successful execution occurs in the device's scope.
