v4l2-async: Unregister sub-device if asc_list is empty","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: v4l2-async: Unregister sub-device if asc_list is empty\n\nWhen my em28xx USB device that uses the i2c tvp5150 driver is\ndisconnected, it crashes.\n\nThe cause is that the tvp5150 i2c module uses v4l2_async, but\nthe em28xx driver does not since it predates v4l2_async.\n\nIn that corner case sd->asc_list is empty, so\nv4l2_async_unregister_subdev() never calls v4l2_device_unregister_subdev().\n\nModify the code so that, if sd->asc_list is empty,\nv4l2_device_unregister_subdev() is still called.","state":0,"publishedAt":"2026-09-17T16:11:13.738+00:00","modifiedAt":"2026-10-19T09:05:34.229+00:00","affected":[{"ecosystem":"Vendor
