Service interruption via malformed virtual-function message
Published Aug 13, 2024 · Updated Oct 29, 2024
Out-of-bounds write in AMD Radeon RX 6000 and PRO W6000 graphics PMFW allows local users to interrupt GPU service via a malicious VF. PMFW insufficiently bounds-checks a message received from a virtual function, allowing malformed input to write outside the intended bounds. Exploitation requires local low-privileged control of a virtual function; AMD does not disclose whether the resulting interruption hangs or resets the GPU.
