In the Linux kernel, the following vulnerability has been resolved: usb: core: port: Deattach Type-C connector on component unbind connector_unbind() is the mirror of connector_bind(), but it is missing the symmetric call to typec_deattach() that connector_bind() makes via: if (port_dev->child) typec_attach(port_dev->connector, &port_dev->child->dev); When a Thunderbolt dock is unplugged, two teardown paths race: 1. The component framework calls connector_unbind() first, which sets port_dev->connector = NULL without calling typec_deattach(). This leaves port->usb2_dev/port->usb3_dev in struct typec_port pointing at the USB device that is about to be freed. 2. usb_disconnect() then calls typec_deattach(port_dev->connector, ...), but port_dev->connector is alre
