  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/mediatek: dsi: Store driver data before invoking mipi_dsi_host_register  The call to mipi_dsi_host_register triggers a callback to mtk_dsi_bind, which uses dev_get_drvdata to retrieve the mtk_dsi struct, so this structure needs to be stored inside the driver data before invoking it.  As drvdata is currently uninitialized it leads to a crash when registering the DSI DRM encoder right after acquiring the mode_config.idr_mutex, blocking all subsequent DRM operations.  Fixes the following crash during mediatek-drm probe (tested on Xiaomi Smart Clock x04g):  Unable to handle kernel NULL pointer dereference at virtual address  0000000000000040 [...] Modules linked in: mediatek_drm(\u002B) drm_display_helper cec drm_client_lib  drm_dma_helper drm_kms_helper panel_simple [...] Call trace:  drm_mode_object_add\u002B0x58/0x98 (P)  __drm_encoder_init\u002B0x48/0x140  drm_encoder_init\u002B0x6c/0xa0  drm_simple_encoder_init\u002B0x20/0x34 [drm_kms_helper]  mtk_dsi_bind\u002B0x34/0x13c [mediatek_drm]  component_bind_all\u002B0x120/0x280  mtk_drm_bind\u002B0x284/0x67c [mediatek_drm]  try_to_bring_up_aggregate_device\u002B0x23c/0x320  __component_add\u002B0xa4/0x198  component_add\u002B0x14/0x20  mtk_dsi_host_attach\u002B0x78/0x100 [mediatek_drm]  mipi_dsi_attach\u002B0x2c/0x50  panel_simple_dsi_probe\u002B0x4c/0x9c [panel_simple]  mipi_dsi_drv_probe\u002B0x1c/0x28  really_probe\u002B0xc0/0x3dc  __driver_probe_device\u002B0x80/0x160  driver_probe_device\u002B0x40/0x120  __device_attach_driver\u002B0xbc/0x17c  bus_for_each_drv\u002B0x88/0xf0  __device_attach\u002B0x9c/0x1cc  device_initial_probe\u002B0x54/0x60  bus_probe_device\u002B0x34/0xa0  device_add\u002B0x5b0/0x800  mipi_dsi_device_register_full\u002B0xdc/0x16c  mipi_dsi_host_register\u002B0xc4/0x17c  mtk_dsi_probe\u002B0x10c/0x260 [mediatek_drm]  platform_probe\u002B0x5c/0xa4  really_probe\u002B0xc0/0x3dc  __driver_probe_device\u002B0x80/0x160  driver_probe_device\u002B0x40/0x120  __driver_attach\u002B0xc8/0x1f8  bus_for_each_dev\u002B0x7c/0xe0  driver_attach\u002B0x24/0x30  bus_add_driver\u002B0x11c/0x240  driver_register\u002B0x68/0x130  __platform_register_drivers\u002B0x64/0x160  mtk_drm_init\u002B0x24/0x1000 [mediatek_drm]  do_one_initcall\u002B0x60/0x1d0  do_init_module\u002B0x54/0x240  load_module\u002B0x1838/0x1dc0  init_module_from_file\u002B0xd8/0xf0  __arm64_sys_finit_module\u002B0x1b4/0x428  invoke_syscall.constprop.0\u002B0x48/0xc8  do_el0_svc\u002B0x3c/0xb8  el0_svc\u002B0x34/0xe8  el0t_64_sync_handler\u002B0xa0/0xe4  el0t_64_sync\u002B0x198/0x19c Code: 52800022 941004ab 2a0003f3 37f80040 (29005a80)",
