+Subject: [PATCH 0562/1050] drm/amdgpu: integer overflow in
+ amdgpu_mode_dumb_create()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+args->size is a u64.  arg->pitch and args->height are u32.  The
+multiplication will overflow instead of using the high 32 bits as
+intended.
