CVE-2025-71294

Local system crash via unchecked buffer ring

Published May 6, 2026 · Updated May 6, 2026

NULL pointer dereference in the amdgpu driver in affected Linux Kernel releases allows local users to crash the system during GPU initialization. In amdgpu_device_ip_init(), the code reads buffer_funcs_ring->sched.ready without checking whether disabled SDMA left buffer_funcs_ring NULL. Exploitation requires a Linux host using the amdgpu driver with SDMA disabled; the documented consequence is loss of system availability.
