CVE-2023-52814

Local system crash via unchecked RAS context

Published May 21, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel amdgpu allows local users to crash the system during device initialization. amdgpu_device_init dereferences the RAS context without checking whether amdgpu_ras_get_context returned NULL for hardware lacking RAS support. Exploitation requires local low-privileged access and a relevant AMD GPU without RAS support; the documented impact is limited to service interruption.
