  "summary": "drm/vmwgfx: reject DX_BIND_QUERY without a DX context",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/vmwgfx: reject DX_BIND_QUERY without a DX context\n\nvmw_cmd_dx_bind_query() unconditionally dereferences\nsw_context->dx_ctx_node->ctx.  Userspace can trigger a NULL pointer\ndereference from any render-node fd by submitting an execbuf with\ndx_context_handle == SVGA3D_INVALID_ID and a SVGA_3D_CMD_DX_BIND_QUERY\nopcode in the command stream: dx_ctx_node is left NULL and the kernel\noopses on the assignment.  The same NULL is then re-read in\nvmw_resources_reserve() via vmw_context_get_dx_query_mob().\n\nAll sibling DX handlers fail-close on a missing dx_ctx_node using\nVMW_GET_CTX_NODE().  Use the same pattern here, returning -EINVAL up\nfront before any relocation state is published.",
