Kernel crash via zero-sized display plane
Published Jan 19, 2025 · Updated May 11, 2026
Divide-by-zero in Linux 6.11 through 6.12.9 allows local users to crash the kernel through a crafted AMD display plane state. The amdgpu dm_get_plane_scale function divides scaled dimensions by zero when a destination plane has zero width or height during cursor-mode evaluation. A local user must reach the DRM atomic ioctl path on a system using the AMD display driver; the resulting kernel oops interrupts service.

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.
